Symposium 4: 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. Not surprisingly therefore, lightweight armor technologies based on ceramic and glass materials have been developed providing levels of protection against a wide array of ballistic threats. Despite this reality, current knowledge and understanding is 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. This deficiency in 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 presentations on a range of topics including superhard ceramic materials, metastable or “far from equilibrium” ceramic materials, novel processing science for advanced ceramics and glasses such as field-assisted sintering and additive manufacturing, advanced characterization methods, hierarchical-structure designed material or multi-scale materials-by-design strategies, fundamental property-structure-process relationship studies such as complexion transitions, dynamic behavior and inelastic deformation mechanisms, and fundamental ballistic behavior are planned. If you are interested in giving a presentation related to one of these special topics, please contact the symposium organizers listed below.
