摘要：

Since 1980, some papers present experimental results which clearly demonstrate that the effects of induced anisotropy are quite pronounced, but at this time few authors have checked the predictions of their constitutive relations in such experiments. This paper describes experimental results performed on a true triaxial apparatus which allows 90°C-rotations of principal stress directions. Therefore induced anisotropy created by an initial loading may be studied. Then, an elastoplastic model with isotropic and kinematic hardening is developed. Its predictions for anisotropic effects are in good agreement with experiments.
