This short example demonstrates usage of FEA tool for pressure vessel lifecycle prediction in regard to ASME regulations.
FEA software, when properly tempered by comparisons with test data, can be highly helpful to provide better answers for many cases.
The purpose of this analysis is to show that this pressure equipment is capable of withstanding the operation for its intended life cycles. Pressure and temperature is changed for operating condition. Due to the stress range induced by pressure and temperature variation, fatigue crack can be initiated at the discontinuity where fatigue strength is very weak.
The base code for the demonstration is ASME Sec.VIII, Div.2,part.5 (‘10 ED.& ’11 ADD.)
