|Abstract:||Hard soils/ soft rocks (HSSR) are natural materials where the bonds between particles have important contribution to their strength and stiffness. Progressive rupture of these bonds affects irreversibly the hydro-mechanical behavior of these materials. Most of the existing models follow the idea that bond degradation depends on accumulated plastic strains. Such is the case of the model used to describe the mechanical behavior observed in oedometer and isotropic compression tests performed on marls.|
