In this paper, fracture mechanism, position and direction of crack initiationof mixed mode fracture in several ductile materials are tested, and stress distributions of which are analyzed.
The predicted valued of the fatigue limit of crack initiation the fatigue limit offracture, and the non-propagating crack length agreed well with the experimental values.
