Nearly all of the mechanical behavior studies of armor ceramics, to date, have involved the characterization and testing of pristine ceramic material. However, ballistic impact causes a strong shock front to propagate rapidly through the ceramic before much penetration can occur. A strong shock wave can result in localized compressive failure and fragmentation of the ceramic before its amplitude is attenuated below the compressive strength of the ceramic. The goals of this effort were to (1) create shock‐fractured ceramic using test assemblies which maintain the intergranular coupling and high density of the ceramic, (2) characterize the extent and homogeneity of the fragmentation and dilatation of the ceramic, and (3) test the compressive dynamic behavior of the shock‐fractured ceramic under conditions of confining pressure. This effort will provide data to support models of the penetration resistance of fractured ceramics including degraded moduli, failure strength‐strain, and post‐failure characterization of the erosive properties of comminuted ceramic and penetrator materials.
