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