Abstmtet-A probabilistic model for prediing fatigue crack growth rate and cycles to reach a given crack iength is presented. The stochastic chamcterixations of cmok growth parameters c and m in the Paris-Erdogan and Forman Iaws are investigated based upon crack growth experiments. According to the s

A model is developed in this paper to describe the nucleation and early growth of fatigue cracks. Polycrystalline materials are modelled as a set of elements (grains) with random properties. It is assumed that the resistance to damage of neighboring elements is mutually independent and follows the s
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
