Abstract
The capabilities of two different constitutive relations for the modelling of undrained triaxial tests on water-saturated loose sand are compared. The hypoplastic model represents a relatively simple model based on rational mechanics whereas the chosen elastoplastic model by Di Prisco belongs to the non-associative plasticity with combined hardening. Both models perform qualitatively well in spite of some discrepancies in comparison with experiments. A modification of the hypoplastic model is tested showing both an improvement as well as additional malfunctions in the model behaviour.
