Abstract: The failure assessment method based on non-linear fracture mechanics has been developed to show the integrity of high temperature components.J-integral is the feasible parameter to represent creep-fatigue crack growth, but there are many difficulties to calculate accurate J-integral in the component.Though finite element analysis and/or boundary element analysis are currently the most powerful tool to evaluate J-integral in complex structure, they require much man-power, cost and know-how.This paper shows various simplified methods to evaluate J-integral for creep-fatigue crack growth, and a comparison of the round-robin results with the experimental and detailed numerical results.
