Two high-strength ceramic materials (boron carbide and titanium diboride) have been subjected to both planar shock and long-rod penetration, and their response has been characterized with time-resolved particle-velocity measurements. In symmetric planar impacts at 1500 and 2200 m/s, shock stresses ranged between 20 and 50 GPa. To examine the ceramic response to divergent waves, targets containing a ceramic layer were impacted at a nominal velocity of 1600 m/s by a 2-mm diameter tungsten penetrator at normal incidence. Penetration targets were built with, and without, a steel cover plate to examine the influence of confinement. Preliminary wavecode analyses of the ceramic response are included. 10 refs., 5 figs., 6 tabs.
