Abstract

An elasto-plastic constitutive model was established in order to describe the stress-strain behavior of normally and over-consolidated sand for static loading in a wide stress region. The fundamental concept herein is based on the assumption that sand can be regarded as an isotropic material. The proposed model which involves eight parameters consists of two set of the yield, plastic potential and hardening functions. These functions are expressed based on a few basic assumptions and experimental evidences obtained from the multi-step stress path tests under 0. 1 MPa-10 MPa confining pressure. This model can give good qualitative prediction of shear and volumetric strains for triaxial compression tests with various stress paths on normally and over-consolidated sand in a wide stress region.
