Local stress - Strain conditions of textured polycrystals under high pressure

The polycrystalline material is simulated as a stochastic continuous medium , and for its description the theory of random fields is used. For such mat erials the tensor of concentration of stresses (strains), which connects lo cal stresses (strains) with their external values, is defined and calculate d. The various approximations for calculation of these operators are receiv ed. The numerical results are obtained for the textured polycrystalline qua rtz rock. The analysis of influence of texture for polycrystalline quartz i s conducted.
