| Abstract: | Based on the fluid saturated two phase porous media model, which is constituted with a deformable solid phase and a fluid phase, deduced from mixture theory, a finite element formulation for quasi static analysis is given out. Rational results of one dimensional and two dimensional numerical examples, analyzed with the developed program PMFEMS, are obtained. |
