A time-domain boundary element formulation for the dynamic analysis of non-linear porous media

This paper presents an original time-domain boundary element formulation for the dynamic analysis of porous media. Integral equations for displacements, stresses and pore-pressures, based on non-transient fundamental solutions are considered. Elastoplastic models are also dealt with by the present methodology, extending the applicability of boundary elements to model complex porodynamic problems. At the end of the paper, a discussion concerning two numerical examples is presented, illustrating the potentialities of the new procedure.
