Abstract

A three-dimensional integral equation arises in the application of the boundary element method to transient dynamic problems of solid mechanics. The formulation has been given by Achenbach/ The time-domain boundary element formulation to solve this integral equation using constant elements has been implemented by Cole et al/ To improve the accuracy of this method, higher- order shape functions in space and time have been used by Israil and Banarjee^ for two-dimensional problems. The numerical implementation of BEM for the time domain spherically symmetric transient problems has been given by Wang and Banerjee/ In this paper, a new and simpler fundamental solution for spherically symmetric transient elastodynamic problems is introduced. The BEM inte
