Abstract

Velocity of the lateral motion of cylindrical, 9 mm diameter 20 mm length, samples impacted by WHA impactors of 5-mm thickness was monitored by VISAR at the different points of the sample surface at distance of 1 to 4 mm from the sample impacted edge. The impactors were accelerated in the 25-mm pneumatic gun up to velocities of about 300 m/sec. Integrating the VISAR data recorded at the different surface points after the impact with the same velocity allows to obtain the changes of the sample shape during the initial period of the sample deformation. It was found that the character of the lateral motion is different for samples made of WHA and commercial Titanium alloy Ti-6Al-4V. 2-D numerical simulation of the impact allows to conclude that the work hardening of the alloys is responsible for this difference.
