Modeling Sand Behavior Under Partially Drained Stress Paths

Yaghtin, M. S. / Lashkari, A.

Abstract Soil behavior is conventionally studied under fully drained or undrained conditions. However, general drainage with complete control on both pore volume 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. Using the concept of loss of uniqueness, onset of instability under partial drainage is studied.
