Analysis of Shock and High-Rate Data for Ceramics: Strength and Failure of Brittle Solids

Abstract

Ceramics based on composition of the light intermetallic compounds, have demonstrated considerable success as a barrier material in armor applications. The exceptional strength-to-density ratio of ceramic plays a crucial role in the positive performance of ceramics in the terminal ballistic environment. Even the higher density ceramics, such as tungsten based materials, show promising behavior in space-limited armor applications. The implementation, optimization and evaluation of ceramic in armor systems benefit from the rapidly growing power of computational analysis and simulation. Production codes such as EPIC. CTH, ALE-3D, among others, are making large strides toward the accurate and efficient simulations of the wide-ranging armor and anti-armor applications of concern. Central to the confident computational simulation of the performance of ceramics in the terminal ballistic environment is, of course, material response models, which describe the character of the failed and comminuted ceramic including fragment size and distribution.
