Abstract

Fatigue life of materials is composed generally of a crack initiation phase, in which the damage develops on a mesoscopic scale, followed by a propagation phase, usually, of one dominant crack until failure. From a practical standpoint, it is essential to have an appropriate probability distribution law of the fatigue crack initiation life in order to determine the optimal inspection frequency. In the present study, a stochastic model is developed to deal with a such problem, where microcracks development is simulated until the formation of the dominant crack. fatigue crack initiation life is obtained for different plastic strain ranges and a probabilistic distribution law is adjusted on the computed results in the case of a 316L austenitic stainless steel under a constant amplitude of plastic strain.
