SURFACE RESPONSE OF AN ELASTIC MEDIUM TO NORMAL PRESSURES APPLIED OVER CONSTANT AND EXPANDING CIRCULAR AREA.

Abstract

The response of points at the surface of an elastic half-space due to applied normal pressures are determined for two distributions of the loads: (a) a uniform time decaying normal pressure applied over a fixed circular area on the surface z = 0; and (b) a time decaying pressure pulse which acts over a surface area of increasing radius. The surface displacements are obtained by means of integrations in space and time of the expressions, given by Pekeris, for the response of the medium to a concentrated point force with a step function distribution in time. A computer code has been developed for each loading case. Some typical numerical examples are presented. (Author)
