Notes:
A practical elastoplastic constitutive model for granular materials is presented. And themodel is suitable for description of the material behaviour for a wide range of stresses, including thosesufficient to cause particle crushing. With a limited number of model parameters, the model canpredict the confining-pressure dependent stress-strain relation and shear strength of granular materialsin three-dimensional stresses, especially of variation of shear strength and dilatancy characteristicsdue to particle crushing under high confining pressure. The model parameters, which have clearphysical meanings, can be determined from the results of isotropic compression test and conventionaltriaxial compression tests. The model performance is demonstrated for triaxial compression tests of asand for a wide range of the confining-pressure from 0.2MPa to 8.0MPa
