Abstract

Barodesy is a frame for constitutive modeling of soils based on their asymptotic properties. This frame allows to derive the constitutive relation by reasoning on general properties of granular materials. The so obtained constitutive relation is a single tensorial equation that expresses the evolution of stress in dependence of the deformation. Common concepts of soil mechanics, such as critical states, barotropy (i.e. the dependence of stiffness and strength on the stress level), pyknotropy (i.e. the dependence of stiffness and strength on density) and a stress-dilatancy relation are comprised in the presented model.
