Interface Defeat of Long Rods Impacting Borosilicate Glass
Abstract
This paper presents an experimental series that investigates dwell and interface defeat for bare brittle materials without any lateral confinement or cover plate system. Reverse impact experiments with gold rods and borosilicate glass targets with a small Cu buffer on top of the glass were performed. Interface defeat was observed simultaneously with five flash X-rays and a 16-picture high-speed optical camera. Experimental results show that the Cu buffer increases the velocity required for penetration by a factor of ~2. Stable dwell is possible for impact velocities up to nearly 900 m/s; whereas without a Cu buffer, penetration starts at impact velocities ~450 m/s with only a short dwell phase after impact.
