Experimental investigations into thermodynamics of dynamic deformation and ballistic perforation mechanisms

Devoted to the experimental study of deformation behavior of materials under dynamic loading. A study of the behavior of coarse-grained and submicrocrystalline titanium rod split Hopkinson-Kolsky simultaneous thermography the sample in real time to determine the fraction of dissipated energy. The behavior of steel under dynamic tension at temperatures of 22 and 250° C. Studied the penetration of the barrier in the formation and removal of tubes at speeds of 101-260 mps. A plant for the study of penetration were studied samples of aluminum 6061. After the experiment, samples were subjected to microstructural analysis using an optical interferometer-profilometer and a scanning electron microscope, followed by treatment with 3D-data of strain relief.
