I want to know how to do fatigue analysi. - 10/20/11 11:10 PM

Hi,

This is ravikrishna.actually we are using stainless steel as material.
we selected endurance curve and run the analysis. can you please help me out what are the load cases.

System temp. 100 & -8 deg. centigrade

Pressure is 420 bar.

as per project spec, system having 720 cycles / year. we took 20 years of life cycle, so total life cycles we take it as 720*20 and this value entered in load cases. is it ok?
