Description
High velocity projectiles cause severe damage to target materials upon impact. The target material is subject to high pressure and temperature over a very short period of time. This work studies the effects of Lexan projectiles impacting A36 steel at velocities between 3 km/sec and 6 km/sec. The damage zone develops in the target within 5 microseconds. Some steel materials go through a reversible phase change when subject to elevated temperature and high quasi-static pressure. It is unknown whether A36 steel experiences this phase change during high velocity impact. The objective of this work is to investigate if any permanent phase change can be measured in the target material after impact.
