Fatigue Crack Propagation Characteristics in HAZ of A106 Gr B Steel Pipe Weldments
초록
In this study, residual stresses of the weldment were calculated by finite element analysis(FEA) and experiment. And, the crack closure behaviour and fatigue crack growth characteristics in field of residual stress of A106 Gr B steel pipe weldment were investigated under various stress ratio. Obtained results are as follows. I)
