Sets out the conclusion of the system of equations of motion of a deformable medium because of its grain boundary structure. There was defined a method for calculating the thermal and stress-strain state on the basis of the field equations of medium flow. These equations are needed to analyze the impact of the stress-strain state on the dynamics changes in the body microstructure in the processes with intense deformation. In the form of differential equations have been obtained analytical expressions relating the 32 parameters characterizing the state of the deformed polycrystalline body. Body is a heterogeneous structure consisting of two thermodynamically interacting components - continuous medium and the grain boundary one.
