The comments below, slightly edited, are provided to
stimulate thought about the direction that our FD&E committee should take in
the near future.
As I see it, one of the big problems with the group is that
everyone is ready to listen, but far fewer are ready to speak. I am very aware
of this, because I am as guilty as anyone. I come and I listen and learn, but
have never done a presentation. My perception is that there is less research
being done, so there is less to share. And the research that is being done is
being done within small consortia which generally means the results are
proprietary and cannot be shared. As far as the former issue (less research),
that seems to be a function of tighter budgets and, as someone else mentioned,
the perception by upper management that the questions have all been answered.
It must be, if it's in a commercially available code, right?
Personally, I really feel I need the committee. It is my best way to keep
abreast of the industry. It is how I know if I'm keeping up, so to speak.
However, for my employer to continue to support it, they have to see some
benefit to them, not just me. As my boss put it, his interests lie less with
getting me from 90% to 95% proficient (his numbers, not mine), and more with
getting my coworkers from 20% to 50% proficient. That means training
opportunities are always important. It also means that when I do presentations
and small investigative projects here for the benefit of my co-workers, I would
be allowed to share those with the committee. But those presentations might be
too "remedial" to be of use to most of the committee
members.
That's my two cents worth up front. I'm looking forward to the meeting next
week.
Michele Wegscheid
Al -- Thanks for keeping me on the FD&E distribution
even though it's been quite a while since I've been able to attend these
meetings on a regular basis. I sympathize with and relate to most of the
comments people have made with regard to restricted travel budgets, conflicting
management and business priorities, etc. Most of us simply don't have the
flexibility and/or budget anymore to regularly attend a wide variety of unfunded
fatigue/fracture technical meetings.
I think Mike Mitchell's offer of integrating many of the traditional FD&E
functions into the ASTM E08 meeting structure is a good one (and I personally
would support it). Of course, an obvious down-side would be that the traditional
FD&E people would no longer be able to independently select meeting sites
and times. On the positive side the broad agendas of these big ASTM meetings
would give ground vehicle fatigue life prediction and design people a wider
range of reasons to justify their participation to their technical managers.
If an integration of E08 and FD&E activities is considered seriously, I
personally would favor a blending/adding of FD&E interests into the existing
E08 subcommittee/working group structure to promote more active, ongoing
interactions between the ground vehicle fatigue/fracture people and the
aerospace/power generation/government fatigue and fracture folks who have
primarily focused on ASTM E08 (and before that E09 and E24) as their technical
forum. I think this kind of blending and challenging of different traditional
and emerging approaches to fatigue/fracture/damage analysis would be very
healthy for the whole fatigue life prediction and design community. In any case,
good luck and let's keep in touch. -- Rich Rice
A lot of interesting and constructive input from many. J.
O. Almen (GM Res. Lab.)wanted SAE FD & E to be participating forum,
"not ruled by academic people" because "academic people want a
publication and
the industry people want something that works". The success will come only
when we join academic and industry efforts in a productive and streamlined
manner. We all are busy and now a days have no or little
funds to support projects outside our work. But we all have to pitch in to make
the committee a success. ATV project had several leaders over time and it was
not streamlined for whatever reason. I think the
organization structure is good but we need to balance material between academia
and the industry if possible and more emphasis needs to put on application. That
will bring in more interest.
Currently, I see the following automotive industry needs:
1. How do we substitute lighter materials without jeopardizing strength and
fatigue?
2. What are the root causes of structural degradation over time and how do we
handle elastomer fatigue?
3. How can we increase quality of our fatigue analysis? Vendors have been
pushing their products as "black boxes" to the managements and to the
new users. They claim many things but upon using people are finding many issues.
That is not helping the industry. Perhaps, they should explain their methods
etc. in this forum.
4. More and more polymers are substituting metals. How do we assess their
durability properly?
5. There are a lot of questions on the fatigue of mig and laser welds in
different materials in context of complex automotive structures.
6. A fatigue design guide document from the committee will certainly be helpful
and will bring much required visibility.

Please let the group know that there is interest in the world, but FDE
needs to change to be relevant. ...etc...
#2 Education is the thing, a uniform design / test philosophy needs to emerge
from the committee.
#3 You need to promote the hell out of what you will become, no more passive
stuff....etc

... Some how you need to figure out what the customer base needs and wants.
...
We reinvented SEM in
Detroit
about 10 years ago when the meetings had dwindled to less than 5 participants
down from 50 or more in the 1970's. We dropped the dinner meetings, put out free
sandwiches and added tours along with the informational meeting. We started
getting 20-30 to turn out. Sometimes 60 would show up. I've been gone for three
years now and have no idea if it still works. But FD&E needs to constantly
reinvent itself - if you intend to remain viable.
After all, GM is building entirely different vehicles compared to when we first
started there. Maybe you should be going to the industry leaders and ask them
"What do you need most?" and see what you get? It is not the way
we went years ago when FD&E was new, but what the heck, it is now
mature with commercial software available that takes the worry out of being
accurate. Now it seems to me that you need understanding how to link it all
together, i.e. the ATV project. Good old GM will fail to participate
and Ford is confused and DCX is being run from
Germany
with the
USA
groups all have a very bad case of Not Invented Here syndrome.
If you can not be relevant to the current users, than maybe it time to take it
off of life support and let it die.
Here is what I'd do:
* I'd be putting out a web site where questions can be asked of us.
* A monthly newsletter pushed out via email to users.
* Poll the T1 management as to their needs.
Now do understand that GM & DCX & Ford management does believe they have
the problem in hand, but we old users know that the Emperor Has No Clothes.
You should be able to find enough users to support a scaled down FD&E
version anyway.
Best of Luck

My areas of greatest interest are: r
relating "old" Juvinall/Shigley fatigue strength
data (and its
conservatism) to new strain-life data, typically expressed as median rank data,
tying FEA to constant amplitude fatigue, and then,
tying FEA to cumulative damage,
correlation methods/processes relating stress analysis and fatigue
testing.
In my current assignment, I have very limited time available to actively pursue
these interests. They will, however, become very important to our division over
the next 5 years, as we move to a duty cycle based fatigue damage design
philosophy (my prediction) ...

Al,
....etc...
My offer still stands -- we would make accommodations within the ASTM E 08 for
the whole FD&E group, you could keep your name if you want (minus the SAE,
of course :o) ) and form two subcommittees; one for the fatigue effort and one
for the surface enhancement people. There would be no intervention
into your doings and we would hope that there would be mutually beneficial
interaction. My personal hope is that this would occur because I would certainly
hate to see the FD&E disbanded --- there have been too many wonderful
contributions to the application of fatigue of materials and structures from
this great group of people to have it fall by the wayside!
If you want, we could discuss additional details -- phone #928-864-3719
Mitch :o)
ps: you might notice that ASTM and ESIS have a partnership! The European
Structural Integrity Society is our counterpart in the EU and the partnership
has been very beneficial in bringing the European "thinking"
and technology into the ASTM efforts to go International. SAE had
"hoped" to go "International" but from what I've observed,
have failed to do so effectively. Just recently, on a trip to
Sao Paulo
, Brasil with Topper and Landgraf for an SAE Fadigua 2001, the guys in SAE
Brasil didn't even know about the FD&E efforts until we told them about your
group. So, having affiliation with SAE seems somewhat nonproductive for
dissemination of information on fatigue.

Sorry this is late, I have been traveling in Europe.
I will not be able to attend the planning meeting in either Oct. or Nov.
MTS travel policy at this point is "no travel that does not directly impact
a customer or job". It looks like this policy will remain in place for at
least another year. Our biggest worldwide business base (the automotive
industry) is currently in a 'freeze all capitol and wait to see what happens'
mode. That means that MTS has very little potential for major new orders in the
Vehicle Dynamics area. Travel and other non-essential expenditures are all
reduced or cut completely until further notice. The company is attempting to
only cut critical staff as a last resort, so many other expenses must be reduced
to maintain jobs (salary has been frozen).
I don't see this changing for several years even if the auto industry picks up.
It always takes awhile for budgets to loosen again after a few bad years in a
market, especially considering that major systems take over a year to deliver
and install (and get paid for).
I think that sums up MTS's involvement (or lack thereof) for some time to come.
Regarding the specific questions (my personal responses are):
1) Renew the vitality: Some interesting and relevant projects would help. Many
of the companies think that the fatigue analysis problems are history now that
it can all be done by computer (just run MSC!).
Possible new subjects might include:
a) FEA confirmation for fatigue analysis (some work was done on this
a few years back)
b) Further work on weld fatigue (we started to get into this further
in the component test group but it didn't take off). I know that some work
has been done on this in the past.
c) More work with cast metals. Some work (particularly cast
aluminums) has been done by this group in the past. What about cast irons
and cast steels? We introduced this several years ago and got some interest
but those of us who originally championed it got busy on other projects and
it languished.
d) Publish the fatigue properties handbook. This will give visibility to the
group and show value (in a form that companies can use) for the work done.
2) Improve work of committee:
a) Get some interesting projects (in a healthy economy) and interested people
will support and participate.
b) We also need to somehow educate the business community on how much remains to
be done, and how inaccurate current fatigue life prediction methods really are
(in spite of them having been committed to software with the corresponding
IMPLICATION that it is all proven, solid technology that can now be successfully
utilized by drafters running FEA). This may be one of the biggest single issues,
particularly when we consider that most engineering companies these days are
managed by professional Business,
Finance, and Accounting people, not the engineers that first developed the
company and understood the limitations of the technology (and could see through
the marketing hype).
c) PR PR PR. The committee does not have the visibility
that it once enjoyed.
3) Beneficial to my company:
a) Work with virtual models for fatigue based analysis is a good subject, and
the ATV project is a good one, but we need better publicity and broader
participation (which would likely come with better publicity).
b) FEA accuracy/considerations for fatigue analysis.
c) Establish root science behind fatigue. We are currently curve fitting only.
We don't know the actual physics (at the material level) behind accumulated
fatigue damage. This is still a huge limitation.
d) Modeling issues for FEA and fatigue (filets, transitions, etc.), meshing
considerations, linear vs non-linear elements, etc. might be useful.
f) Using FEA to predict a rotating principal stress and assess
damage accordingly.
4) Other suggestions: Don't give up the ship after a few tense years. We need to
maintain communications and contact but may have to limit expenditures for a few
years while the economy recovers. I seem to recall
going through similar problems in the mid 70's, yet somehow we recovered.
This also sets back my hope to get the SAE/U of Iowa Fatigue Design Short Course
going again. We have to at least wait until people in the automotive industry
are traveling again before it is worthwhile to invest in another mailing, prep
costs, etc. to see if it has a chance to get going after the hiatus we are now
in. I was hoping to approach a couple of the major supporting companies (that
had sent many students in the past) for a small deposit for seed money. I think
that would be fruitless at this time.
I suspect we are not the only one's in this situation.
Maybe the SAE FD&E needs to move to a 'dormant' mode, with emails and other
communications continuing but formal meetings curtailed until the economy picks
up again????

Al and John:
... Good luck to you in coming up with good solutions. I do hope we continue the
committee for many years despite the difficulty of getting people to come and
participate. We lost the short courrse to changing company thoughts on employee
participation in non-direct productivity.

#====================================================================
I have appreciated the group's interest in hearing about my work. I have learned
some things that should be useful to a rubber component supplier (examples - how
to think about real-world loading cenarios/histories, needs of OEM engineers). I
have made some valuable contacts in the fatigue world.
My sense is that the FD&E committee has had an unusually strong sense of
community for a technical society of its type, which I view as one of its
strengths. I would like to keep in touch with the group for these reasons.
I think the group is suffering from competition for people's travel time/money
with the commercial fatigue software vendors, who are now aggressively marketing
their training services and analysis tools. It might
help if vendors could be persuaded to somehow hold their events/training in
conjunction with FD&E meetings?
Perhaps management and newer engineers in industry do not have an adequate
understanding of the value of this kind of forum. Maybe the group could invite
some talks from industry executives to provide broader perspectives (and to give
input on how the group might provide value to industry). Training events would
be of obvious benefit to newer engineers. OEM companies may be in a position to
promote to their suppliers the benefits of participating in FD&E.
With Best Regards,

#====================================================================
Regarding the attendance problem, from Ford we usually drive, thus even in an
economic downturn we can usually get support for the trip. If we were required
to fly we would not be able to come, even in "good"
$ climates.
My feeling is that FD&E suffers from some lethargy. People attend, listen to
talks, but not a lot is going on. Recently the ATV has attracted attention, but
it too now is slowing down a bit in the activity of those interested. This may
change just as quickly however if some topic stimulates this group, and I think
we should give it another chance before giving up on further work.
A lot of good work has been done on the ATV and one objective we have is
to create a summary book/web document of all that has
occured so that others can more easily build onto it. The work so far would make
for an excellent case study or guide book for virtual prototyping; a topic that
is of interest to many corporations. The problem is that doing the work is much
harder for us "fatigue folks" than the previous FD&E projects.
Probably 4x as hard as working on the biaxial shaft, and perhaps 10x as hard as
the Keyhole tests and theory. Hard or not it is worth getting done. We should
make a list of the missing items, break them down into manageable pieces and
finish the job properly.
The other divisions:
Life Prediction Division: many of us now use commercial codes to perform life
predictions. Thus there is less interest in improving the theory. "let
Somat or NCode or Fedem or MCS or LMS etc deal with it." I have some
personal views on this: specifically that this will stifle research and
innovation too, an undesirable event, because most of the codes still cannot
predict life within a factor of 10, but
the answers now come out in nice pretty color plots so we can live with the
commercial results. My guess is that we could probably let the Life Pred. Div.
go dormant for awhile until a future
need arises, or when a few dedicated souls feel strongly enough about some topic
to study it and revive the division.
Component Test: We don't seem to have a lot of interesting components that
people want to test at the moment. I think that this would be easy to fix,
however; we could do a material or process subsitution (shot peening?) on an ATV
suspension arm. We could try some aluminum welds. Laser welds? Bolts?
What we need for each of these is a plan/list of
items that need to be done, and when the list is presented
some volunteers to help do the test. We should all be capable of helping in
"easier" testing like this.
If we cannot get anyone to volunteer for testing some
components we should let this div. go dormant.
Surface Enhancement Div: I think this group is doing fine but could probably use
some interaction with the "fatigue test" section of FD&E. Testing
a shot peened component would be
ideal. Shot peened weld? Lets pick something.
Road Load Data Div.: Road load collection/analysis are a highly computer and
software intensive field these days. It has been difficult for FD&E members
to offer much to increase the state of the art. Generally we buy something to
collect "road loads" and accept the results. With only a few $/Gbyte
for a disk the older summarization problems have gone away. Its is easy now to
just collect everything
and let the standard programs handle the summary. Unless there are some
objectives here that we can contribute to, FD&E should probably let this
division go dormant for awhile.
Materials Properties Div.: Getting good data sets is always of interest to all
FD&E members. Getting volunteers to run
the data, with a few exceptions, has been a problem. The difficulty with the
previous FD&E data collection is that we were never able to get legal
clearance to publish data sets.
Creating good data is fairly cheap. $5K-10K per set. We should all be able to
ask our Corps. to fund at least
one data set each per year- and to contribute the data for the public good. We
could make this a price of
admission? AISI has gotten a great deal of interest in their 3 year project. We
should easily fill the same
needs at FD&E for other materials. I think that this division should be left
as is, but that we should all
contribute something to this, ANNUALLY!
My apologies for getting a little wordy here.

#==================================================================
from: Chin-Chan
Chu
What I see are missing:
-- lack of participation: People seem to show up because they are expected to;
very few seem to be thinking about how we can benefit from pulling our resources
together. Rather, the majority seem to
be waiting for orders at best.
benefit to participating members unclear: Minimum travel
expense probably would not be an
issue if the members can bring back progress, fruitful thoughts, and an idea of
better processes.
-- productive organization: The divisions, probably a good idea during active
multiaxial-fatigue-years, have almost become dividing forces. To work properly
in this structure, we definitely need focus. ATV
was a good one; but how the divisions can work together, or challenge each
other's capability to achieve the final digitized process was not well planned.
Based on the above crude observations/thoughts, what I see are needed:
-- a Project/Goal: A couple of ideas I have are
a) Use of current fatigue method for reverse engineering:
Establish procedures to proactively suggest design changes (in material,
geometry, and manufacturing processes), rather than wait for new designs and
perform another durability analysis).
b) Characterize (and thus database) not only fatigue properties
of base materials, but also items of significant impact on fatigue;
for example, joining methods, stress history characteristics such
as multiaxiality, mean stress/overload.
-- buy-ins of the participants and their employers
-- a re-org: forget about the divisions right now. only break into divisions
later when we see specific tasks, which requires little input from the other
divisions, forming.
#=======================================================================
I agree with much of what has been said and only have a few things
to offer.
1) A critical component is having a goal (or goals) that *everyone* can
contribute to. One of the problems with the ATV project was that some
individuals felt that they had little to offer the project. A few tried starting
unrelated and secondary side projects but these did not go far or garner much
support. Should there be a mechanism for starting these "task forces"
from the executive committee level so that they receive some minimum buy-in and
support? -- this is not to suggest that individuals in ones and twos can't do
side projects on their own.
As mentioned by others in this forum, it is very important to align our goals
with the needs of our industries so that we can justify the time we spend
working on these projects.
2) Should there be a further "price" for attendance ... namely
participation? FD&E is nominally a working group, but it seems lately we all
get together to watch just a very few individuals work.
Perhaps there is a method by which we could extort (not a good word but the only
which comes to mind) participation from the peanut gallery? Maybe we could set a
limit of two meetings without contributing something, however small. Sure it
might chase off some people, but it might at least re-invigorate debate. For
starters, how about $75 for attendees and $20 for participants.
3) I have been troubled by the increase in the number of presentations which are
primarily to sell some product, be it software or hardware. I would dearly like
to get the presentations back on topic -- perhaps we
could designate a certain percentage of presentations that would have to be on
current or proposed FD&E projects (ATV, etc.), and then leave say 1/3 or
less for non-FD&E business. Further, let's not get
presentations on the schedule just to fill a time-slot. I think that this
would go a long way towards bringing our focus back onto our projects.
4) (Lifted from a conversation with Conle & Fatemi): Why not keep the
meetings centralized so that we can maximize the participation of those who
can't afford to come otherwise. We don't need to tie it to any
particular member's workplace. For instance, how about
Grand Rapids
at some inexpensive motel. We don't need a plant tour ... although they are
fun.
John Bonnen
#=============================================================================
A planning meeting is certainly needed. Maybe we should consider revamping
the structure of FD&E. Eliminate the divisions and start working as a
whole. The divisional structure
seems to have fragmented the committee over the
past several years. We also need to find an area of activity where most
everyone is interested. I think most are interested in reducing vehicle weight
and improving fuel economy.
One possible area to consider is material substitution i.e. design, manufacture
and test an aluminum (welded tube or cast) control arm for the
ATV. How light could we get it and still have it survive. Go out on the
edge.
The shot peening group should be involved to insure durability. Other materials
include magnesium and plastic composites. I haven't thought this
out completely but it's a start and I think we could get everyone
involved.
We could meet at a more central location like
South Bend
,
IN
or the
Chicago
area.
Russ Chernenkoff
#==========================================================================
Hello Russ. The only reason I was not planning to go is remotness of
Fargo
and travel expenses to fly my
students over. Over the past 24 years I have
been attending these meetings myself, and over the last 15 years with my
students. I have always been happy with what I have learned from
technical exchanges at the meeting.
I have not noticed a significant drop in attendance
or participation in recent years, compared to my early days, but I don't
have quantitative data like you may
have. Here are my thoughts/suggestions for future
meetings:
1. Do not choose a remote site (unless it is
Palo Alto
or
Seattle
!) for future meetings. People like Alan who are in remote areas can still
host/organize the meeting, but they can do it in a better suited location,
such as in
Detroit
area.
2. Pick a good topic of interest to many people for the Tech Session and have
all presentations of the Tech Session related to that topic. This can be
done at about the same time the
meeting location is decided, so that there is
enough time for organizing a good Tech Session. We could perhaps also
invite a well known keynote speaker
on that topic, similar to what ASTM sometimes
does.
3. Carefully choose a common interest AND challenging theme/topic of research
with a good/very interested leader, in which many members are
interested/willing to participate, rather than our current small somewhat
unrelated projects with small participation. For example the previous
successful ones I remember were the SAE Keyhole round robin program and
the multiaxial fatigue program. The
ATV project I think lacked good leadership,
even though it enjoyed a lot of enthusiam and participation at the
beginning.
I sure hope this meeting was the first and only cancellation, as my students
and I gain a lot from these meetings.
Ali
#==========================================================================
I agree with almost everything that Ali Fatemi stated. 1. Do not choose a remote
site for future meetings.
2. Pick a good topic of interest to many people for the Tech Session and have
all presentations of the Tech Session related to that topic. Ideally try to tie
it to core activities of the committee such as the ATV.
3. Carefully choose a common interest AND challenging theme/topic of research
with a good/very interested leader. The ATV could be that topic but it needs
stronger leadership. Maybe a professor would be willing if we fund some of his
work.
4. Corporations should be further encouraged to donate money. We should form a
task group that seeks donations. Corporations will be motivated if:
A) we develop technology that is relevant to their day to day problems
B) we allow companies to "showcase" their technology, I think we have
done
this already in the past and it is for this reason that MTS has sponsored
past activities
I would propose to have a 1 day planning meeting of key leaders of the committee
to brainstorm how to reinvigorate the committee and then follow through on some
of these ideas before we schedule the next official SAE FD&E meeting.
Christoph Leser
Al: The Fatigue short course died not from lack of good teaching, but lack of
Michigan
people attending. It was suggested we move the course to
Chicago
for better enrollment. We couldn't since if the course were
to cancel, we could not pay the cancelation fees. Should SAEFDE move to the
south suburbs of
Chicago
?
You know that lack of enrollment, traval or attending SAEFDE meetings is
dictated by industry to eliminate things that don't apply directly (right now)
to products. ASTM has the same problem of getting volunters.
Much SAEFDE work recently has been done by only a few people from industry, and
more from academia. Most of these academic people have studied with older
faculty such as Fuchs, Morrow, Topper, Stephens, and Socie. I wonder if we can
keep the younger academics involved?
ASTM integration does not sound very feasible to me. Also they meet all over the
USA
, not in the midwest.
The most common questions asked at the short course were: Where can I find
material properties, and how can I shorten my tests. These could be good topics
to consider.
I think it wise to reduce the splintered effects of our current Division
structure as mentioned by others.
Could the HO Fuchs award be of more help?
Good luck next week and hopefully we will keep SAEFDE going for many years.
Ralph Stephens
Al -- Thanks for keeping me on the FD&E distribution even though it's been
quite a while since I've been able to attend these meetings on a regular basis.
I sympathize with and relate to most of the comments people have made with
regard to restricted travel budgets, conflicting management and business
priorities, etc. Most of us simply don't have the flexibility and/or budget
anymore to regularly attend a wide variety of unfunded fatigue/fracture
technical meetings.
I think Mike Mitchell's offer of integrating many of the traditional FD&E
functions into the ASTM E08 meeting structure is a good one (and I personally
would support it). Of course, an obvious down-side would be that
the traditional FD&E people would no longer be able to independently
select meeting sites and times. On the positive side the broad agendas of these
big ASTM meetings would give ground vehicle fatigue life prediction and design
people a wider range of reasons to justify their participation to
their technical managers.
If an integration of E08 and FD&E activities is considered seriously I
personally would favor a blending/adding of FD&E interests into the existing
E08 subcommittee/working group structure to promote more active, ongoing
interactions between the ground vehicle fatigue/fracture people and the
aerospace/power generation/government fatigue and fracture folks who have
primarily focused on ASTM E08 (and before that E09 and E24) as their technical
forum. I think this kind of blending
and challenging of different traditional and emerging approaches to
fatigue/fracture/damage analysis would be very healthy for the whole fatigue
life prediction and design community.
In any case, good luck and let's keep in touch. -- Rich Rice

John,
Dan Lingenfelser and I just met with some others at Cat to discuss our
suggestions for the SAE FD&E Committee. I'll try to give you a few summary
points.
Consensus was that the FD&E committee was valuable and should be
continued.
Valued areas highlighted were:
- Fatigue Short Course (training) -- this training differentiates the
committee. It has the right mix of instructors and is valuable to train people
in industry. It is something the committee can point to that is a major
accomplishment.
- Networking -- The meetings provide a regular forum for updates. It provides
a vehicle to network with other professionals in industry.
We would like to maintain our offer to host the Spring meeting and would
suggest trying to use the meeting to revitalize the committee. Our suggested
theme would be Virtual Prototyping. With this topic and outside expert speakers,
we could use this meeting to gain visibility for the committee.
