Recently two hypoplastic constitutive models were proposed by Bauer for modelling the long term behaviour and wetting deformation of weathered and moisture sensitive rockfill materials. The models take into account the influence of the current density, the effective stress state, the moisture sensitive solid hardness and the rate of deformation. In the present paper the performance of these models is evaluated by comparing numerical simulations with experiments obtained from a water sensitive granular material. In particular triaxial compression paths and creep deformation under deviatoric stress states are considered. Finally, the proposed constitutive model is used to study the influence of a degradation of the solid hardness on the long term behaviour of a hypothetical fill dam.
