Interface defeat of long rods impacting oblique silicon carbide

This paper presents experimental results for an unconfined oblique ceramic impacted by long gold rods. The obliquity angle of the ceramic was 60, the impact velocities varied between 0.90 km/s and 1.65 km/s. The ceramic impact surface was either bare or covered with a copper plate as a buffer. Dwell of the rod was observed by means of multiple X-ray images. The effect of the obliquity angle and the buffer on the dwell-penetration transition velocity was examined and compared to existing normal impact data.
