A theory of fatigue crack growth based on the concept of damage accumulation is presented which takes some account of the effect of periodic-random loading. The Dugdale model of plasticity is used to calculate the distribution of the energy dissipated during stress cycling in the plastic zones of a
Cychc pre-stress increases subsequent fatigue crack growth rate in 2024-T3Sl ahrminum ahoy. This increase in growth rate, caused by the pre-stress, and the increased rate, caused by temper embrittlement as observed by Ritchie and Knott, cannot be explained by the crack tip blunting model alone. Each
A modification to the model of Weir ef al. for surface reaction and transport controlled fatigue crack growth has been developed to explicitly account for the effect of load ratio on environmentally assisted fatigue crack growth. Load ratio was found to affect principalfy gas transport to the crack
