Focused Session 2: Protective Ceramics – Fundamental Challenges and New Developments
Ceramic and related composite materials possess qualities that make them useful for applications involving high-velocity impact. Fundamentally, such intense events are governed by momentum transfer moderated by high-rate inelastic material behavior and failure. Understanding material behavior and failure under these conditions is highly challenging due to the nonlinear, nonuniform, coupled interactions between dynamic stresses and the inherent multi-scale material structure, from atomic defects to processing flaws. This can lead to the initiation and growth of a multitude of inelastic deformation mechanisms such as phase transformations, dislocations, twinning, stacking faults, microcracking, fracture, and others, resulting in fragmentation of the solid body. By identifying and understanding underlying mechanisms, their consequences, and processing-structure-property relationships, material behavior can be controlled. This Symposium is focused on the fundamental challenges and new developments associated with the topics listed below. In addition, special sessions on: (1) Ultrahard ceramics, (2) High-throughput experimentation and data-driven techniques, and (3) Dynamic behavior, are planned. Presentations addressing these topics and those listed below are welcome.
