摘要: This paper reviews several constitutive models for the load response of bulk solids. Constitutive based on microscopic concepts and continuum principles are presented. The review demonstrates need a generalized model that can predict stress-strain behaviour cohesive powders, since none have yet been found. However, two identified as having sufficient versatility to be chosen candidate application food agricultural powders. One is an elasto-viscoplastic critical-state theory, includes seven material parameters in equations. second uses endochronic theory characterize response, requires 15 formulation. Both used isotropic anisotropic loading conditions, well monotonic cyclic loading.
