Abstract: In this paper, a yield surface of a new constitutive model for anisotropic and small-strain conditions is presented based on energy equation. Compared with yield surface of modified Cam-Clay model (MCC) and from experiment, the new yield surface is closer to experiment result than the surface of MCC. A function is adopted to modify the hardening rule for expressing the behaviour of soil in small strains. The new constitutive model is compiled in a finite element program. The computed results from the new model are compared with the experimental results. The prediction shows that the new constitutive model can better simulate stress-strain characteristics of soil clay than MCC.
