Development of induced anisotropy during shear deformation of plane granular assemblies is investigated by introducing statistical characteristics of fabric and contact forces. The introduced microstructural parameters are explicitly related to the measure of deviatoric load by considering conditions of static equilibrium. Verification of the relationship between parameters of anisotropy, average forces and external loads is presented based on numerical simulation of tests on plane granular
