Sand Hypoplasticity (von Wolffersdorff, 1996)


Sand hypoplasticity is an advanced incrementally non-linear constitutive model, an outcome of an extensive research at Karlsruhe University in 1990’s. It incorporates pressure- and density-dependency of soil behaviour. Its response has been validated using a number single and finite element simulations of various geotechnical problems. When combined with so-called intergranular strain concept (Niemunis and Herle, 1997), it is capable of predicting small strain stiffness degradation and cyclic loading effects.

    When using this model,what is the value of the state variable?
