Abstract

The torsional impact response of a flat annular crack in an elastic cylinder of finite radius is investigated in this study. Laplace and Hankel transforms are used to reduce the problem to the solution of a set of triple integral equations. These equations are solved by using an integral transform technique and the result is expressed in terms of a singular integral equation of the first kind. The singular stress field near the crack tip and the dynamic stress-intensity factor are determined. Numerical results on the dynamic stress-intensity factor are obtained to show the influence of inertia, geometry, and their interactions on the load transmission to the crack tip.
