Abstract

In this work a particular fundamental solution of the 3D Time Domain BEM formulation is proposed to give the desired generality, accuracy and stability. Based on this fundamental solution it will be possible, at a near future, to treat initial conditions, velocity and displacement, and to deal with integral representations for stresses and velocities with great stability and confidence. 1 Introduction Since the first work on the 3D time domain BEM formulation, written by Karabalis and Beskos [1], the stress integral representation has not yet been successfully implemented. This lack in the literature is present until the work due to Coda and Venturini [2], where initial conditions have been consistently treated, as well as a good idea on the desired
