A coupled elastoplastic damage model is proposed for the description of strongly anisotropic sedimentary rocks. In order to describe the inherent anisotropy of the material, a scalar anisotropy parameter is introduced using the concept of fabric tensor. Using this parameter, an anisotropic plastic m
