| Abstract: | Various types of hardening laws have been in the formulation of the elasto-plastic constitution relationship of soil. In this paper, the influence of different hardening laws on the matrix of elasto-plastic modulus [D]ep of soil is studied, and the appraoch for establishing the yield locus and plastic potential is proposed. The general expressions of [D]ep which can be used is the finite element analysis for the three-Dimensional, plane strain and axisymmetrical case are devide. |
