Abstract: In this paper, Biot's u-U wave propagation formulation for saturated porous media is implemented on commercial FE codes. The new method couples the solid and pore fluid phases using two FE meshes, one for the solid and the other for the fluid phase. The fluid-solid coupling is implemented using dashpots and user-defined material subroutine. The proposed method is applied to published example and consistent results are obtained. The wave propagations from dry to saturated media are studied. The two dilatational waves are clearly observed in the vicinity of fluid solid interface. In the end, effects of the permeability and loading frequency on the wave profiles are also studied. © 2013 AIP Publishing LLC.
