These proceedings contain current research from industry, academia and government organizations, working on opaque and transparent ceramic armor. Papers on novel materials concepts for both vehicle and body armors are included, as well as papers that explore the relationship between computational modeling and property testing. These papers were presented at the Proceedings of the 30th International Conference on Advanced Ceramics and Composites, January 22-27, 2006, Cocoa Beach, Florida. Organized and sponsored by The American Ceramic Society and The American Ceramic Society's Engineering Ceramics Division in conjunction with the Nuclear and Environmental Technology Division.
