Stochastic Diffusion Models for Fatigue Crack Growth and Reliability Estimation

  • B. F. SpencerJr.
Part of the International Centre for Mechanical Sciences book series (CISM, volume 334)


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.
