✦ Synopsis

A hybrid "nite element method is proposed for the thermo-mechanical analysis of porous materials with pore pressure. Arbitrary n-sided polygonal elements based on the Hellinger}Reissner principle are used to mesh the heterogeneous domain. The validity of the proposed method is veri"ed by a simple analytical solution and the results obtained by the conventional "nite element method (ABAQUS). Irregular local stress distribution on a porous material with randomly distributed holes is predicted by the proposed method.

The aim of this contribution is the development of a finite element formulation tailored to capture strong discontinuities in fluid-saturated porous media. Thereby, strong discontinuities are considered as the final failure mechanism within localization problems. The failure kinematics are governed

We consider a coupled problem of the deformation of a porous solid, ¯ow of a compressible ¯uid and the electrical ®eld in the mixture. The governing equations consist of balance of the linear momentum of solid and of ¯uid, continuity equations of the ¯uid and current density, and a generalized form
