Analysis on the Behavior of Nonpropagating Fatigue Cracks under Steep Stress Gradients

A mechanism for the formation of nonpropagating fatigue cracks ahead of a notch root is presented. The stress gradients near the elongated notch root along with the propagation of short crack and the resulting nonpropagating crack lengths anpc are estimated. The local stress which is higher than the...
