How do I define the load history in fatigue analysis of pressure vessel having design pressure of 8.25 Mpa?

13 July 2015 1 2K Report

i have to analyze the pressure vessel in the code aster in which i need to define the load history . The only thing i know is design pressure. anyone who can tell what load history i should define and of how much time? Tanks in advance

Dr.O.P. Gupta

Fatigue analysis is relevant for cyclic loads. It may be only a few or many cycles of partial or full loading/ unloading (of a pressure vessel !)during a day or week. This is what I feel is meant by load history, in general.
