Abstract
This paper presents a convolution quadrature time-domain boundary element method for a fluid-saturated porous medium. Wave analyses for fluid-saturated porous media using the conventional time-domain boundary element method (BEM) are not popular since it is difficult to obtain the closed form of timedomain fundamental solutions. To overcome the difficulty, in this paper, a convolution quadrature method (CQM) is applied to time-domain boundary integral equations. The scattering problems of an incident plane wave by cavities in the poroelastic media are solved with MPI for validating the present method.
