Fatigue Analysis

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.

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.

if i do not have SN CURVE DATA what i can do ?

Hi @ank

What data do you have so far?

density,yield stress,ultimate stress,young modulus,poisson  ratio.

hi every one, im new member !

I am reading the e-book follow your suggestion.

Now, i dont have SN or EN data. 

so i wonder how can i setting material properties or evaluation for my analysis ?

can u explain me more a bit plz.

thanks for your kindly help !
