โœฆ Synopsis

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 stochastic characterixatians of c and m, the statistical distributions of crack growth rate du{dN and cycles to reach a given crack length are found using the Monte-Carla simulation technique. The predicted results agree closely with those of crack growth experiments of aluminium alloy LylS-cz. It is shown that this model may be used in engineering.

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

A review of several statistical and probabilistic approaches to the problem of fatigue crack growth shows that many Markov models are equivalent in that they express the probability density of the crack length at time t as solutions of the Kolmogorov, or Fokker-Plank, equations. Further, it is shown

The phenomenon of fatigue crack closure has attracted continued interest over recent years. This paper concerns itself with one aspect of the phenomenon namely the effects of a single asperity on the crack face close to the crack tip and under dominantly plane strain Mode 1 loading conditions. The m
