Abstract

The transient Green's function for the 2D Lamb's problem is derived for the general case where both, source and receiver point are situated beneath the traction-free surface of the half-plane. It is used to calculate boundary ele- ment approximations for subsurface structures in the time-domain without the need to discretize the surface of the half-plane. The time convolution is performed numerically in an abstract complex plane. The solution pro- cedure proved to be more efficient for problems concerning the half-plane than techniques using the full-space fundamental solution. 1 Introduction Only a few amount of publications exist in boundary element methods which employ a Green's function as kernel of the boundary integral
