Study of wave propagation in poroviscoelastic solid using boundary element approach

Abstract eng:
The present paper is dedicated to numerical solving of three dimensional boundary—value problems in porovis coelastic formulation. The poroviscoelastic formulation is treated as a combination of Biot’s theory of poroelasticity and elastic— viscoelastic correspondence principle. Boundary element method (BEM) and boundary integral equation (BIE) method are applied to obtain Laplace domain solution of three—dimensional boundary—value problem Modified Durbin’s algorithm of numerical inversion ofLaplace transform is used to perform solutions in time domain.
