The Gaussian stationary stochastic load process is considered to cause fatigue crack growth in randomly inhomogeneous materials. The Paris-Erdogan model is applied and the time when the crack length reaches a critical value (lifetime) is determined as a random variable. It is shown that random varia
From previous investigations of the mechanisms of both fracture and fatigue crack propagation, the static fracture model proposed by Lal and Weiss may be thought as reasonable for describing fatigue crack propagation in metals at both low and interm~iate stress intensity factor ranges AK.

Abmtmct-In this paper a crack propagation model based on Tomkins concept (df/dN = Ae,, . o) has been developed using the theoretically developed cyclic plastic xone sixes. The crack propagation rates are found to be functions of stress intensity factor, Elber's efTective stress range ratio, cyclic y
