A continuum model for granular materials: considering dilatancy and the Mohr-Coulomb criterion

Acta Mechanica, 2001•Springer
In this paper we will explore the consequences of the Mohr-Coulomb criterion on the
constitutive equation proposed by Rajagopal and Massoudi [1]. This contunuum model
which is based on the earlier works of Cowin [2] has also the ability to predict the dilatancy
effect which is related to the normal stress effects. At the same time, if a proper
representation is given to some of the material parameters, this model would also comply
with the Mohr-Coulomb criterion. We also present, as a special case, an exact solution for …

Summary
In this paper we will explore the consequences of the Mohr-Coulomb criterion on the constitutive equation proposed by Rajagopal and Massoudi [1]. This contunuum model which is based on the earlier works of Cowin [2] has also the ability to predict the dilatancy effect which is related to the normal stress effects. At the same time, if a proper representation is given to some of the material parameters, this model would also comply with the Mohr-Coulomb criterion. We also present, as a special case, an exact solution for the case of simple shear flows.
