Plane mechanics and kinematics of compressible ideal granular materials

Abstract

The question of the correct formulation of constitutive equations to describe the mechanical and kinematic behaviour of granular materials such as soils and powders remains one of discussion and controversy. The purpose of this paper is to make some contributions to this discussion with particular reference to compressible materials. To this end we put forward some suggestions for consideration, while recognising the existence of alternative approaches to the problems discussed, and of differences of opinion which remain to be resolved.
