A stochastic model of fatigue crack propagation under variable-amplitude loading A stochastic model of fatigue crack propagation under variable-amplitude loading Ray, Asok; Patankar, Ravindra 1999-03-01 00:00:00 This paper presents a stochastic model of fatigue crack propagation in ductile alloys that are commonly encountered in mechanical structures and machine components of complex systems (e.g. Aircraft, spacecraft, ships and submarines, and power plants). The stochastic model is built upon a deterministic state-space model of fatigue crack propagation under variable-amplitude loading. The (non-stationary) statistic of the crack growth process for center-cracked specimens is obtained as a closed form solution of the stochastic differential equations.
