A study of plastic strain localization under static and dynamic loading using the StrainMaster non-invasive strain measurement system

Static and dynamic testing of specimens specially designed for studying the localization plastic deformation in AMg6 D16 alloys were performed on then electromechanical Testometric machine split Hopkinson pressure bar using StrainMaster system noninvasive measurement shape deformation. Displacement strain fields are plotted special-shaped subjected to static loading. Comparison between experimentally obtained results numerical simulation made with account kinetics microdefect accumulation examined material demonstrates good agreement accuracy ~20%. The tests their consideration evolution defect structure confirm concept mechanism associated processes microdefects.
