Thanks a lot for the answer Erik, that discussion you linked was very helpful.
I will try using the fatigue tool to see how my model behaves.
I Just wanted to ask one more thing, is there a way in which I can specify the time for the simulation and see how my part performs?
Because my objective with the simulation is to model a real life vibration test that is run on battery packs to check for multiple failures. I can use a similar approach that is in the above linked discussion, but my concern is I don't want to design a part that has a life of 15 minutes. Rather, I want to see how it performs under 15 minutes of those loading conditions.
