Abstract
The governing equations of fluid flow through a deforming porous medium are considered for saturated and unsaturated flow. A uniaxial compression test cell is described. A strain-hardening formulation is presented based on nonlinear poroelasticity and "crushable-foam" plasticity models, which have been verified and applied in dewatering analysis of fibroporous media. Two- and three-dimensional models, including solid and liquid phases, are analyzed based on the isotropic poroelasticity, crushable-foam plasticity behavior, and contact theory. Definition and determination of material parameters are based on compression tests. A finite element analysis is implemented for a uniaxial compression test and is verified based on experiment data. A contact model is examined. Important mechanical quantities for solid and liquid phases, such as pore pressure, velocities, plasticity strain, deformation, and fluid behavior, are presented. A comparison of numerical solutions with experimental results shows good agreement.
