Abstract
Effect of residual stress on creep crack growth behavior in ASME P92 steel was investigated using compact tension (CT) specimen. Tensile residual stresses were generated ahead of crack tip by loading in compression beyond yield and then unloading. The maximum region of residual stress was obtained by numerical simulations which calculated the models with various notch radiuses and penetration loads. After pre-compression, creep crack growth tests were carried out on pre-compressed and original CT specimens to study the effect of residual stress. Furthermore, the corresponding approach on predicting creep crack growth behavior for components with residual stress was also investigated.
