• A three-dimensional isotropic stress-dilatancy model is proposed. The model is formed on the basis of the basic hypothesis that the shear deformation of granular materials results mainly from the sliding between grains. The model is also based on such a new concept relating to shear mechanism that the position of sliding contacts is closely related to the applied stresses and accordingly shifts in turn as shearing proceeds. The general stress-strain increment relations obtained from the model contain the influence of stress path in a general form. It is verified that the stress-dilatancy equations derived from the model agree weel with the experimental results under the conventional and true triaxial stress conditions.
