Theoretical Prediction of Strain Localization in Anisotropic Sand by Non-coaxial Elasto-Plasticitypic sand. In order to accurately predict the onset of strain localization in inherent anisotropic sands under multi-dimensional stress condition, a state-dependent critical state constitutive model was proposed. The anisotropic critical state line was modified by incorporating micro-structure inform

Modeling Sand Behavior Under Partially Drained Stress Pathsme and pore water pressure leads to a wide spectrum of behaviors which may not be delimited by drained and undrained ones. Herein, a critical state bounding surface plasticity model is employed to simulate partially drained behavior of sand samples sheared over a wide domain of drainage conditions.
