Abstract
This study presents a novel peridynamic model for the prediction of fatigue crack growth rate with the effects of overload and underload. The modified Wheeler models for underload, overload and overload-underload combinations are applied to peridynamic fatigue equations. The capability of the proposed peridynamic fatigue model is demonstrated by considering fatigue crack growth on a single edge-notch plate subjected to constant amplitude loadings with overloads, underloads, and overload/underload combinations. The accuracy of the proposed peridynamic fatigue model is verified by comparing the predicted fatigue crack growth with experimental results.
