An finite element-finite volume hybrid method for large deformation analysis of porous media

A finite element-finite volume hybrid method for large deformation analysis of porous media is proposed. The porous media is considered as 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 discredited 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.EI04483-487+4932
