The fall 2009 FDE meeting was help October 13 on the University of Michigan Dearborn campus. It was hosted by Hong Tae Kang. There were 20 attendees on site and 5 remote attendees.
The following technical presentations were made.
“Fatigue Damage Equivalence in Vibration Testing” - Dennis J Polehna, Yung-Li Lee, and Ben J. Palmer – Presented by Ben Palmer
“Effects of stress concentration on crack initiation and propagation in ambient air and corrosive environment” - Tyng Tyng Lee
Vehicle Prognostics: Understanding Usage Severity and Potential Damage Accumulation for a Combat Vehicle Suspension Component- Mark Pompetzki, Brian Dabell, Joseph Gothamy, James Bechtel – Presented by Dan Lingenfelser
Tom Cordes presented an update on the fatigue challenge activities and Dan Lingenfelser presented an application of the challenge in Failure of Engineering Materials course.
Steve Haeg is investigating resurrection of the Fatigue Design Shortcourse. While there is strong support for the shortcourse, challenges include seed money for startup and sponsorship. Steve will continue to work on this.
There was also some discussion about the development work on the AFS material database. They are in the process of populating it with more case material properties and debugging.
We have lost contact with a number of members due to job changes so Dan is seeking a volunteer to contact members and update contact information.
The next meeting will be held jointly with ASTM E08 on Fatigue and Fracture the week of May 17, 2010 at the Renaissance St. Louis Grand and Suites Hotel St. Louis, MO. In addition to the regular committee meeting, there are workshops planned on “Probabilistic Methods in Fatigue Life Forecasting” and on “Surface Crack Shape Evolution”.
