A Low-Cycle Fatigue Design Combined Finite Element Analysis about Pressure Vessels

Abstract:

The study of Low-Cycle fatigue showed that strain is more important parameter than stress for describing fatigue property of materials .Exactly obtaining regional strain of the structure by analysis is key in fatigue design of complex structure .Therefore, the analysis and solution by finite element is very necessary. The maximum elastic and plastic strain at the nozzle junction of a pressure vessel under several loadings are calculated by using ANSYS software .Then crack forming life is calculated by using the N.E.Dowling formula .
