Fatigue Analysis as per ASME VIII Div.2
Fatigue Analysis as per ASME VIII Div.2
(OP)
Hello,
we are designing a pressure vessel as per ASME VIII Div.1 and it works in cyclic service, so we use ASME Div.2 for the fatigue analysis. We have a program called nozzlepro, with which we can perform the fatigue anaysis but this program only allows the temperature to be variable (the pressure stays as a constant). But this is not our case, because both T and Pr are variable. Could anyone give us a tip about how to proceed in this case?
Thank you!

For a fatigue analysis, make sure that you are checking the longitudinal weld seams, the circumferential weld seams, the head-to-shell joints, all of the nozzle connections, external support clips, saddle/skirt connection, and many other locations.

Think you meant to say "the whole vessel"
