Abstract
Crack propagation is a major task in the design and life prediction of fatigue-critical structures such as aircraft, offshore platforms, bridges, etc. Experimental data indicate that fatigue crack propagation involves a large amount of statistical variation and is not adequately modeled deterministically. The lectures presented herein discuss the basic analysis and use of fracture mechanics-based random process fatigue crack growth models that can be represented by Markov diffusion processes. For completeness, the random variable models are presented as a special case of the random process models. The use of the models in fatigue reliability estimation is also discussed.
