Numerical calculation of the elastic and plasticbehavior of saturated porous media

this investigation the _eld equations governing the mechanical behavior of a ~uid!saturated porous media are analyzed and built up for the study of elastic dynamical problems and quasi!static problems in case of elastic plastic material behavior[ The investigations are limited to small deformation in order to apply a geometrical linear approach[ The two constituents are assumed to be microscopically incompressible[ A numerical solution is derived by means of the standard Galerkin procedure and the _nite element method[
