✦ Synopsis

A stochastic model describing fatigue crack growth under random overload peaks is presented. A Poisson flow of overloads superimposed on a base-line constant-amplitude cyclic load is considered. Under the above assumptions the total retardation time is presented as a stochastic process governed by the intensity of overloads. Expressions estimating lifetime under prescribed reliability level are derived.

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 n
