Abstract

Abstract

Based on the particle crushing of granular material,which affects the mechanical characteristic of stress dilatancy,and the power function used to describe the characteristic stress ratio,it is developed that the yield surface and its expression of the characteristic state.It is also analyzed the change law of the yield surface according to the value of parameters.The yield surface of characteristic state will be the same as the modified Cam-clay model when the parameter equals to a special value.Finally,combined with proper isotropic compressed conditions and unified hardening parameter,the yield surface can be applied into the constitutive model for sand,which can predict the tests results well,and describe the mechanical characteristic of sand exhibiting particle crushing reasonably.
