| Abstract: |
| A finite element-finite volume hybrid method for large deformation analysis of porous media is proposed.The porous media is consideredas two-phase material with a solid skeleton and a pore fluid phase.Governing equations for the porous media consist of an equilibrium equation and a continuity equation.Based on the u-p formulation and updated Lagrangian method,the equilibrium equation is discretized in the space domain by finite element method,and the continuity equation by finite volume method.Two numerical examples including one-dimensional finite elastic consolidation and dynamic analysis of an embankment are used to illustrate the performance of the proposed method. |
