Advanced critical state model based on the theory of hypoplasticity designed for the modeling of fine-grained soils with various degrees of overconsolidation.
Nonlinear model with stress-dependent stiffness based on the theory of hypoplasticity adjusted for the modeling of sand and gravel in loose or dense state.
Classical representative of elasto-plastic critical state models suitable for the modeling of normally consolidated and moderately overconsolidated fine-grained soils.
