A bounding surface plasticity model recently updated based on cyclic simple shear tests of UC Berkeley (Wu, 2003). An option to apply residual strength Sr is available for the user. The Sr can be applied at a user selected pore pressure ratio Ru.
- bounding surface
- critical state
- effective stress
