Abstract Statistical criteria of the start of macroyield for various mechanisms of shear formation, including the correlation coefficient of tangential microstresses, which makes it possible to take into consideration the mutual influence of the single crystalline grains, are formulated for a model of a polycrystalline material, a microinhomogeneous medium possessing local anisotropy of mechanical properties and consisting of grains with a cubic type of crystalline lattice. Known criteria of strength are compared and it is shown that they are particular cases of the proposed statistical criteria for certain values of this correlation coefficient.
