Abstract
.Different continuous elastic-plastic constitutive models (Mohr-Coulomb model, modified Cam-Clay model, modified Drucker-Prager model) are analysed with respect to their ability to simulate hysteretic behaviour of granular materials under the low-cyclic kinematic loading. The analysis is done in the framework of the quasi-static infinitesimal deformations. In case of the Mohr-Coulomb constitutive model, hysteresis degeneration into the straight line is revealed. Energy loss due to the hysteretic behaviour is studied. It is shown that horizontal areas representing the elastic behaviour are significantly longer for the Mohr-Coulomb criterion.
