Fatigue Analysis

Recommended Posts

hi,

It depends on the method of fatigue analysis you are opting for like S-N method etc. 

For S-N method, you need S-N curve property of the material and can also use some empirical relations certain fixed parameters required for such analysis.

It is given in optistruct help

Actually there is a lot you can input provided what you have.

 

I would suggest you to refer fatigue theory available on OptiStruct help and also tutorials.
