In the present study, the Goodman-Cowin theory is extended to incorporate plastic features to construct an elasto-visco-plastic constitutive model for flowing dry granular materials. A thermodynamic analysis, based on the Mu¨ller-Liu entropy principle, is performed to derive the equilibrium expressi
