摘要：
In this paper we resume some remarks upon the model for dry granular materials formulated in [19] which generalized the distributed theory of Goodman & Cowin [24] by allowing the possibility of rotations of grains. Firstly, we reconsider the balance equations for micromomentum and energy by bearing the bulk and rotational effects of granules in mind; secondly, we derive the constitutive relations and define the dissipation function; thirdly, we specify an appropriate equilibrium state for dry granular materials in order to obtain additional informations on constitutive fields.
