THE INFLUENCE OF DEFECTS LOCALIZATION AND STABLE MEZOPARTICLES FORMATION ON THE BEHAVIOR OF MATERIAL UNDER IMPACT LOADING

The paper is devoted to the investigation of behaviour of material und er impact loading. Two structure levels of deformation was took into a ccount. At microlevel the conditions of existence of stable dislocatio n groups formation and their distribution were obtained. These groups were considered as an inclutions with finite mass at the next structur e level of deformation. The influence of the mass and position of the inclusion on the stress field in material was studied. For some partic ular forms of loading it was shown how deformation depends on the char acteristics on the inclusion.
