In order to estimate the statistical variability of fatigue crack growth in metallic structures, a stochastic model is proposed by combining stochastic theory with experimental results. A stochastic differential equation is derived from the stochastic model for fatigue crack growth. By using the solution of the stochastic differential equation, some distribution functions related to fatigue crack growth were derived. Sample functions of fatigue crack growth time histories have been simulated as random processes.

An extended McEvily model for fatigue crack growth analysis of metal structures is proposed in this paper. In comparing with our previous work, the extension is mainly concerned with the following two aspects: (1) the slope of the fatigue crack growth rate curve is regarded as a variable rather than
number of stochastic models of fatigue crack growth under constant amplitude cyclic loading are assessed in the light of experimental data. Particular attention is paid to the predictive performance of the models under a change in the initial crack length and generally it is found that the models pr
