Stress Intensity Factors of Corner Crack in a Quarter-Infinite Solid

Abstract

In this paper, a versatile method for a quarter-infinite body with a corner crack of an arbitrary shape is proposed under two types of pressure;which are constant and linear. And new numerical results are obtained in many cases. Fatigue crack propagation from a corner crack is analized successively with the present method. Moreover, a stress intensity factor of a corner crack is proposed in a simple form for an arbitrary shape.
