Abstract

The axisymmetric dynamic response of a circumferential edge crack in a cylindrical cavity under normal impact is analyzed. Laplace and Hankel transforms are used to reduce the transient problem to a pair of dual integral equation in the laplace transform plane. The solution is given in terms of a singular integral equation of the first kind which has a generalised Cauchy kernel as the dominant part. A numerical Laplace inversion routine is used to recover the time dependence of the solution. Numerical results on the dynamic stress intensity factor are obtained to show the influence of inertia, geometry and their interactions on the load transfer to the crack.
