Abstract
To predict the mechanical behavior of granular materials, the importance of the noncoaxiality; that is, the noncoincidence of the principal directions of inelastic stretching and those of stress, has been recognized in the geotechnical field. In this study, the deformation characteristics during shearing under the effective mean stress constant and the intermediate principal stress coefficient constant conditions are examined by the elasto-plastic constitutive model in comparison with experimental results on Toyoura sand. In constitutive modeling, the anisotropy in the loading surface and the effect of stress rate tangent to loading surface, both of which cause noncoaxiality, are taken into consideration.
