摘要: ABSTRACT Three probabilistic models describing the random fatigue crack growth and predicting its corresponding durability are discussed in this paper. The first is a simple randomization of Paris-Erdogan equation, second discrete Markov chain model third Poisson process model. To examine applicability superiority these models, numerical examples performed over experimentally obtained data twenty center cracked APFH 60 high tensile steel specimens. It concluded that all three give us satisfactory results present study.
