... increased. The residual stress can be reduced to 70%. The reduction of residual stress leads to the variation of fatigue crack initiation, which was derived from the edge center of the as-built part and the edge vertexes of heat treatment parts. For as-built and anneal treatments, the morphology...

... estimation scheme is developed to obtain the material constants. Both in-phase and out-of-phase thermo-mechanical fatigue tests are conducted. A physically based model is developed for correlating crack initiation life based on the experimental life data and predictions are made using the crack initiation...
