Rajendran, A M; Cook, W H

This report reviews high-strain-rate experimental and analytical methods available for characterizing ceramic-material behavior. Also, a discussion on the ceramic failure mechanisms upon impact-loading conditions is provided. Theoretical basis for constitutive and failure modeling of ceramic-type brittle material is discussed. Models that are reported in open literature are reviewed and categorized based on their theoretical approaches. The salient features of a few recently reported constitutive/damage theories, which combine either the micromechanics or the continuum-damage mechanics for the stress-strain relationship with fracture mechanics for damage-accumulation description, are described and tabulated. Recent attempts to employ such models in the calculation of armor-penetration problems are briefly discussed.
