S4: Armor ceramics–challenges and new developments

When properly combined with other materials, ceramic and glass materials can exhibit ballistic penetration resistances significantly higher than monolithic metallic materials. Therefore, it is not surprising that lightweight armor technologies, based on ceramic and glass materials, have been developed that provide levels of protection against a wide array of ballistic threats. Despite this reality, current knowledge and understanding are limited with respect to the effects of a ceramic body’s physical, chemical, structural, and mechanical  characteristics on its local and global response to dynamic contact loading conditions that are characterized by locally large transient stresses, deformations, and temperatures. The deficiency in our understanding of processing–structure–properties–performance relationships has been a hindrance to the development of new materials through conventional and advanced processes, as well as materials-by-design strategies.


This symposium is an opportunity for attendees from industry, academia, and government organizations to meet and participate in open discussions on relevant fundamental and applied research that supports the advancement of knowledge and understanding of the processing–-structure–properties–performance relationships for ceramic and glass materials. Proposed symposium topics are listed below. In addition, special sessions on (1) fundamental terminal  ballistic behavior, (2) ultrahard and superhard ceramics based on B-C-N-O chemistries, and (3) novel concepts and methods for improving properties by engineering ceramic structure at the atomic, nano, micro, meso, and macro length scales are planned. Contributing papers addressing the general symposium topics and/or the special session topics are welcomed. For those interested in participating, but uncertain whether their work fits within the theme of this symposium, please contact the symposium organizers listed below.
