โฆ Synopsis
A new probabilistic model of fatigue crack growth is constructed in which the parameters are explicit functions of the stress intensity factor. There are two versions of this model. These models are applied to a set of fatigue crack growth data. Some comments are offered on the implications of these models in studies in fatigue crack growth.

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
The theoretical study is advanced to describe quantitatively the crack propagation under cyclic loads. The main assumptions accepted are: (a) a crack grows by loading during every cycle, and (b) the specific dissipation energy is a material constant. The latter contains. the known concept by Irwin a
