Book Description
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.

Book Description
Dynamic Response of Advanced Ceramics Discover fundamental concepts and recent advances in experimental, analytical, and computational research into the dynamic behavior of ceramics In Dynamic Response of Advanced Ceramics, an accomplished team of internationally renowned researchers delivers a comprehensive exploration of foundational and advanced concepts in experimental, analytical, and computational aspects of the dynamic behavior of advanced structural ceramics and transparent materials. The book discusses new techniques used for determination of dynamic hardness and dynamic fracture toughness, as well as edge-on-impact experiments for imaging evolving damage patterns at high impact velocities. The authors also include descriptions of the dynamic deformation behavior of icosahedral ceramics and the dynamic behavior of several transparent materials, like chemically strengthened glass and glass ceramics. The developments discussed within the book have applications in everything from high-speed machining to cutting, grinding, and blast protection. Readers will also benefit from a presentation of emerging trends and directions in research on this subject as well as current challenges in experimental and computational domains, including: An introduction to the history of ceramic materials and their dynamic behavior, including examples of material response to high-strain-rate loading An exploration of high-strain-rate experimental techniques, like 1D elastic stress-wave propagation techniques, shock waves, and impact testing Discussions of the static and dynamic responses of ceramics and the shock response of brittle solids An overview of deformation mechanisms during projectile impact on a confined ceramic, including damage evolution during the nonpenetration and penetration phases. Perfect for researchers, scientists, and engineers working on ballistic impact and shock response of brittle materials, Dynamic Response of Advanced Ceramics will also earn a place in the libraries of industry personnel studying impact-resistant solutions for a variety of applications.

Book Description
The RDA ceramic failure model was used to model the behavior SiC and B4C during plate impact loading. The experiments modeled were performed at Sandia National Laboratory. The simulations were performed with a version of the Sandia WONDY-V hydrocode that was modified to run on a PC and to include the RDA ceramic failure model. The model adequately characterizes the two ceramic materials although B4C and SiC exhibit distinctly different degrees of work hardening, strain rate hardening, and damage sensitivity. Both materials experienced damaged (micro-making) on load which was predicated by the model. The experimental unloading data exhibits a reduced magnitude elastic unload wave which suggests that further damage has accumulated after the ceramic reaches peak stress. A strength reducing mechanism such as fatigue, or melting at grain boundaries are suspected as the cause of this unpredicted strength loss. No spall was evident in the measured signals and the model predicts spall will not occur. The predicted axial stress levels were significantly above the estimated spall strengths of the two ceramics. Failure was prevented by positive (compressive) mean stress levels that were maintained throughout the ceramic specimen during the experimental measurement. Therefore, a suggested conclusion is that for tensile failure to occur in these ceramics, the mean stress must be negative (tensile). (js).
