A hot isostatically pressed (HIP) assembly of titanium alloy encapsulated AD995 ceramic, subjected to ballistic impact, is studied in detail. The crack behavior of ceramic confined in this way is studied in a combined experimental and computational effort. Fabrication of the HIP assembly is described. An experiment in which an assembly was impacted with a Lexan impactor at 1560 m/s is discussed, and the resulting deformation of the assembly and cracking of the ceramic are characterized. The Statistical Crack Mechanics (SCM) model for brittle materials is briefly described. The implementations of this model into the Lagrangian code PRONTO and into the Eulerian code CTH are described and used to further study the response of the ceramic during the experiment.
