Durability and Fatigue Seminar

Siemens PLM cordially invites you for an informative and educational day covering the process and best practices for predicting and optimizing product durability and fatigue life on Tuesday, May 1st in Chicago, IL.

This seminar can help you answer questions like:

  • How long will my part survive?
  • How can I correlate my simulation models to match my test based targets?
  • How can I develop a controlled/accelerated test that captures my operational loads?
  • How damaging are the loading environments of our structure?
  • How do we establish and quantify a durability target based on customer data?
  • Why doesn't my part fail at the maximum stress location?

Both simulation and test methods for product durability engineering will be presented side-by-side, integrated methodology.
