and Crack Growth Evaluation Finite Element Analysis Fracture Mechanics Weld Residual Stress
Flaw evaluation method for riser brace arm weld was investigated in case of a flaw is detected in in-service inspection. Weld residual stress was evaluated using 3-D finite element model considering structure of riser brace. Fatigue and SCC crack growth evaluation was performed using evaluated residual stress and stress due to normal operation. Two methods, which are JSME fitness-for-service code and influence function method, were applied to estimation of stress intensity factor to investigate effect of st...
