Stress Intensity Factor of Peripheral Edge Crack around a Spherical Cavity under Internal Pressure Corrected

Abstract:

The singular stress problem of a flat annular crack around a spherical cavity subjected to internal pressure is investigated. By application of an integral transforms and the theory of triple integral equations, the problem is reduced to the solution of a singular integral equation of the first kind. The equations gotten for the case of peripheral edge crack around a spherical cavity is solved numerically, and the stress intensity factors are shown graphically. The results in this paper are basically consistent with the existing literature in special cases.
