In order to better simulated the anisotropy of granular materials, the anisotropic state variable was introduced into the micropolar hypoplastic constitutive model, and the simulation of biaxial compression tests were carried out. The influences of fabric on the width and inclination of the shear band were studied by the FEM and DEM. The following results were found. With the increase of anisotropic state variables, at the same vertical strain, the width and inclination of the shear band remained basically unchanged and the element rotation angle at the same position was increased.
