A Summary of the Prevost Effective Stress Soil Model

Résumé du livre

In the Prevost effective stress soil model, soil is viewed as a multi-phase medium consisting of an inelastic porous skeleton and viscous fluids. The model is a general analytical that describes the nonlinear, anisotropic, elasto-plastic, stress and strain dependent, and strength properties of the skeleton when subjected to a three-dimensional loading. This report presents a summary of the Prevost model. A summary of the model formulation is given with its implementation into the DYNAFLOW finite element code. Test data are compared with code prediction. Several boundary value problems are solved as a demonstration of capability.
