Effect of Specimen Thickness on Delay in Fatigue Crack Growth



The effect of specimen thickness on delay in fatigue crack growth, produced by load interactions in variable-amplitude loading, was examined. Experiments were carried out on 7075-T6 aluminum alloy sheets. The results indicate that delay is a function of specimen thickness. This influence of thickness, along with variations in behavior among different materials, suggest that extensive extrapolation of existing data should not be made.
