Stress intensity factors of a corner crack emanating from a pinhole of a solid cylinder

This paper presents stress intensity factors (SIFs) and fatigue growth analyses of a corner crack emanating from a pinhole of a cylinder under cyclic tension. No such work has been reported in the literature. Stress intensity factors for different crack aspect ratios and pinhole sizes in different diameters of solid cylinder are presented. A larger SIF was found at the smaller crack size of a or c in a larger diameter of a pinhole of the smaller-diameter cylinder. Crack growths at the pinhole edge were found to be faster than those at the cylinder edge.
