On the theoretical modeling of fatigue crack growth

Journal of the Mechanics and Physics of Solids, 2018
Abstract Although fatigue is by far the most common mode of failure of structural materials, mechanistic understanding is still lacking. For example, the fundamental Paris law which relates the crack growth rate to stress-intensity factor range is still phenomenological and no reliable mechanistic model has been established for a given material or ...

A diffusion model for fatigue crack growth

Proceedings of the Royal Society of London. A. Mathematical and Physical Sciences, 1979
Abstract A stochastic model is proposed for the propagation of a fatigue crack. It is shown that fatigue crack growth can be described by a transition density function, and that the probability of a fatigue crack reaching a critical size can be determined by solving the diffusion equation. The commonly used rate of crack growth, da/dN

Bayesian Modeling For Fatigue Crack Curves

1992
An accurate assessment of the propagation of cracks in materials (“metal fatigue”) is important to the structural design and the development of preventive maintenance programs for many engineering structures, including critical aerospace components. Interest is centered on modeling the lifetime process, N(a), which represents the number of load cycles ...

A PLASTICITY MODEL OF FATIGUE CRACK GROWTH

1993
A model of fatigue crack growth is presented in this paper involving the advance of the crack tip in steps accompanied by plasticity and necking. The model accounts for the shape of Regions II and III and it proposes that Region I arises as da/dN approaches the atomic scale.
