Abstract:

Experiments were performed to determine the dwell-penetration transition velocity for an unconfined SiC target impacting a long gold rod. Some of the targets used a small copper buffer to attenuate the initial impact shock which increased the transition velocity significantly by a factor of approximately 2. Transition velocity for bare SiC is approximately 800 ms whereas the buffered targets had a transition velocity of approximately 1550 ms. Once penetration is initiated, X-ray images show significant damage in the target. A possible scaling effect of the rod dimensions could be responsible for the slightly lower transition velocity compared to earlier experiments.
