How to Perform Failure Analysis and Test Correlation

This session will introduce the student to the topic of failure and correlation. Failure analysis is the purpose of performing any simulation. However, understanding what failure is and what it looks like is more complicated and involved than just looking for red spots. How do we determine what theory to use? Or what failure is? For example, just because your design yields doesn't always mean that it failed. With test correlation, uncertainty is everywhere—as in life. Most engineers fail to understand that just testing after analyzing the design doesn’t constitute correlation. If the analysis results are interpreted to suggest the part won’t break and it doesn’t break, the analysis isn’t correlated. Consequently, if the analysis indicates a likely failure location and the part breaks at that location, the analysis isn’t correlated. We will dive into these topics and examine how you can properly predict failure and perform correlation? This session features Simulation Multiphysics and Nastran.
