Fatigue crack propagation is often requited to be assessed especially in thermally stressed and/or stress concentration portions. In these components, the conventional stress classification approach is not easily applied to, and appropriate methods practically applicable to the conditions have not been well established or standardized. The author has been involved in the development of the simplified evaluation methods to evaluate crack propagation behaviors in general loading conditions, which is expected to be applicable to these conditions, without requiring costing detailed FEA of a cracked body. This paper describes the outline of the method together with an example of evaluation referring to the high cycle thermal fatigue test carried our by the French CEA.
