The torsional impact response of a thick-walled cylinder with a circumferential edge crack is considered. Laplace and Hankel transforms are used to reduce the elasto-dyanmic problem to a pair of dual integral equations. The dual integral 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 kernel of the integral equation is improved in order that the calculation may be made easy. A numerical Laplace inversion routine is used to recover the time dependence of the solution. The dynamic singular stress field is determined, and the numerical results on the dynamic stress intensity factor are obtained to show the influence of inertia, geometry, and their interactions.
