摘要：

We propose a two-dimensional modelling of the anisotropy of granular media based on the use of a second order or a fourth order fabric tensor describing the distribution of the contact probability. This fabric tensor-based approach is then combined with a new kinematic localization rule and yields an efficient homogenization scheme for anisotropic granular media.
