✦ Synopsis

A probabilistic crack growth model based on a nonlinear damage accumulation criterion is presented. The damage criterion takes cognizance of the effect of the loading sequence, and is an energy-based function. The simulation results are shown to compare favourably with experimental data of four different types of steels and an aluminum alloy. The predicted results are also compared with that of the linear damage theory and, in general, are found to be superior.

A fatigue crack growth rate in consideration of fatigue damage accumulation and the mean stress on fatigue material elements ahead of a crack tip are derived using Both Miner's rule and the Manson-Coffin relationship. The theoretical equation of fatigue crack growth rate is shown in terms of J-integ
