Hi all,

I have been studying the fatigue analysis methodology of CAESAR recently and have some questions.

1) How does CAESAR calculate the Maximum Stress Intensity for Fatigue cases? Are the formulas the same as those in This Earlier Post ?

2) What is the Code Stress as given in the FAT case output?

3) When we wish to input our own fatigue curves in CAESAR in accordance with ASME Sec. VIII Div.2, do we have to take into account the ratio of the Elastic Modulus given in the fatigue curves to the elastic modulus of the material at the average temperature of the cycle being evaluated? [Please see Equation (3-F.3) In Annex-3F of ASME Section VIII Div.2] Or does CAESAR handle this in the background without the user being aware of it?

Merry Holidays everyone!
