Abstract
A method has been developed for predicting the growth of surface fatigue cracks with allowance for the shape of the crack front under regular cyclic loading and the presence of tensile overloads in the loading spectrum. The crack model is constructed on the basis of consideration of the specific contributions of the mechanisms that determine the advance of the crack. It is shown that allowance for such important factors as the variation in the severity of the stress state along the crack front is essential in model representations.
