Experimental Investigation of Adiabatic Shear Banding at Different Impact Velocities

Abstract

During this report period the final operational stage in development of the new experimental technique have been achieved. This technique enables for studying a fast plastic deformation and development of adiabatic shear bands at different displacement velocities. This technique is being tested using newly acquired measuring devices, i.e. non-contact optical extensometer/displacement gauge, and H.P. fast oscilloscope. Numerical studies of plastic zones in the double shear specimen have been started using the computer code 'ABAQUS'. Finally, some contacts with the French Army Laboratory (ETCA) have been undertaken to prepare steel specimens for a final testing.
