Probabilistic models of fatigue crack propagation and their experimental verification

To study the fatigue crack growth problems and to emphasize the variability of the growth curves in addition to their average growth trend, three stochastic fatigue crack growth models are presented. These models include the Markov chain model, Yang's power law model and a polynomial model. Experimental work is carried out to produce the required fatigue crack growth data, which are then used for verification of the models. Two sets of...
