Abstract :The subloading surface model which fulfills the mechanical requirements for constitutive equations, i.e. the continuity,the smoothness conditions, the work rate-stiffness and the Masing effect relaxation has been extended so as to describe the inelastic stretching due to the deviatoric tangential stress rate for the subloading surface. The model is called the tangential-subloading surface model. In this article, the subloading surface model enabling the description of deformation behavior of a cyclic loading with the tangential rate effect is applied to the prediction of the deformation behavior of sand subjected to a cyclic loading of circular stress path in the π-plane deviating significantly from the proportional loading. The validity of the model and the tangential stress rate effect are verified comparing with the test data.
