BOUNDARY-ELEMENT ANALYSIS OF THE PROBLEM OF A PRISMATIC BODY ACTING ON A HALF-SPACE IN A POROUS-ELASTIC FORMULATION

Abstract

The action of a non-stationary force on a deformed porous-elastic die rigidly interacting with a porous-elastic half-space is analyzed in a 3D formulation, using BEM in combination with the integral Laplace transform. The displacement and flow responses are constructed. The displacement responses are used to demonstrate the effect of formation of Raleigh wave.

Keywords: boundary element, porous-elastic material, half-space, 3D formulation, deformed die, non-stationary dynamics.
