Mesovolumes of materials are the objects of investigation in this paper. These volumes containing significant elements of internal structure of material are investigated by numerical methods of continuous media mechanics. The purpose of the research is numerical modeling of localized deformation at the mesoscale. Results of the calculations show that joint influence of heterogeneities of internal structure of material and action of maximum shear stresses results in localized development of plastic deformation as a system of shear bands. They are accompanied by formation of bulk structural elements, which move as units relatively to each other. It is shown that rotations in the regions of strain localization are higher than in the other parts of the specimen.
