Book excerpt: The overall objective of this MURI program was to develop a new class of lightweight armor materials in the form of layered ceramics and metal ceramic composites. This entailed developing novel processing techniques, extensive dynamic experimental evaluations and modeling as well as new analysis and experimental methods. The research program consisted of four major areas: manufacture of layered ceramics and ceramic metal composites for armor, constitutive modeling and damage mechanisms, ballistic penetration experiment and simulation, and development of advanced experimental and computational methods. Briefly, in the processing area, two versatile routes for production of layered and graded multilayer ceramics have been developed: sequential centrifugal casting and lamination of tape-cast ceramics. In the mechanics and modeling area, microstructural effects on the response and failure in heterogeneous materials under dynamic loads were studied and modeled. New experimental methods were developed with the aid of inverse methods in conjunction with the FEA. Improved computer codes for simulation of projectile penetration were achieved.
