The process of deformation development in a polycrystal with pain interaction is modelled in frames of flat two-dimensional elastic-plastic flow of the media with structure. The processes of a possible fragmentation and a grain boundary segregation influence on the plastic deformations development are considered. The influence of distribution of a work under non-elastic deformation on material structure change and average value of mechanical parameters determination is analising in the presented calculations of deformation of a composite material with damping matrix.
