For arbitrary anisotropy in the linear manifold of singular solutions generating square-root singularities near the crack tip, a special basis is introduced that possesses the same properties as in the isotropic case and provides simple integral representations for the application of the energy fracture criterion, in particular, the conditions of crack deviation from a straight path.
