✦ Synopsis

A stochastic approach to fatigue crack growth under random overload sequences, superimposed on a base-line cyclic load, is described. The approach consists in presentation of the delay time due to the retardation effect associated with the overload peaks as a purely discontinuous Markov process. A numerical procedure based on the KolmogarovPFeller integrodifferential equation is developed. Application of the model is illustrated by examples.
