Abstract

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.
