Introduction

The Asymmetric Continuum Theory may lead us to problems of the induced anisotropy, caused by the defect content, friction and fracture pattern. We consider such a problem of the anisotropy as reduced to the 2D anisotropy caused by an influence of some linear dislocation system. The fracture processes trace the pre-slip structures, which leads to the related anisotropic fracture ability and friction properties. We make an attempt to express the 2D anisotropy, as related to the antisymmetric part of stresses (stress moment anisotropy): for this problem we use the skew coordinate system. The fracture processes trace the pre-slip structure of media revealed in the formation mylonite layers leading to inertia-related anisotropy and related fracture ability and friction properties. To this aim, we have introduced a geometrical approach to the problem of skew and fracture anisotropy.
