fatigue analysis for a given number of cycles

CRI_CFD · September 23, 2023, 14:33

Dear all,

First of all, thanks for taking the time to check my thread.

I am a beginner with fatigue analysis. I need to obtain damage due to the application of 50.000 cycles of pressure inside a pressure vessel. I am using ANSYS Mechnical for this.

The thing is that I can carry out a static structural simulation and then use the fatigue tool to estimate fatigue life of the stucture (number of cycles before failure), damage, safety factor...

But I have no idea how to impose a given number of cycles (for the static results obtained) and compute damage (should be of course D<1).

Is it possible to do this in ANSYS Mechanical?

Any tips will be highly welcome.

Mnay thanks!
