Experimental Study of Interface Defeat in Confined Ceramic Targets

Recent experimental studies by Hauver et al. reveal that the ballistic performance of ceramic targets depends entirely on the state of confinement of a ceramic in a composite target. If the ceramic confinement is preserved, the penetrator is consumed by lateral flow at the ceramic-cover plate interface; this mechanism is known as interface defeat. In the experiments reported in this paper, stress histories produced at the cover plate-ceramic interface and ceramic-back plate interface are recorded with in-material gauges. Velocity measurements, at the back plate free surface, are recorded with VISAR. Partial interface defeat of the L/D 20 tungsten long rods shot at 1. 7 km/s, on composite targets containing alumina and Titanium diboride ceramics, was obtained.
