Book excerpt: To develop a fundamental understanding and quantitative assessment of the dynamic response and failure modes of highly heterogeneous and anisotropic composites of ceramics, cermets, metals, and fiber-reinforced polymeric composites, various specific complementary scientific tasks have been initiated by the participating team members, based on their strengths and expertise. These tasks include development of novel experimental techniques, preliminary experiments, development of micromechanically-based models, and computational tools. As research progresses, these efforts will be continued and will be integrated, in order to effectively achieve the basic goals of this MUH. While the team members have collaborated with each other in various relevant research areas, each one has emphasized one or two necessary research areas, as follows: Sia Nernat-Nasser: Dynamic experiments (Hopkinson/gas gun); dynamic failure of fiber-reinforced polymer composites; micromechanical modeling of compression-induced failure modes of anisotropic heterogeneous ceramics; and modeling of anisotropic effects in pulverized, initially heterogeneous, ceramic layers; Marc Meyers: Synthesis and processing of TiC-NiTi and TiBsub2-NiTi composites; constitutive description of porous ceramics; and quasi-static and dynamic testing of composites; VitaliNesterenko: Thick- walled cylinder experiments on various grades of SiC; experimental investigation on nonexplosive, shear-induced chemical reactions in various relevant compounds; and micromechanical modeling of hot isostatic pressing of metallic alloys; Ken Vecchio: Fabrication of titanium-aluminide composites; microstructural characterization; and preliminary modeling; Dave Benson: Computational techniques to efficiently integrate various coupling physics into computational codes, including reactive flow models, statistical crack mechanics, and improved integration of finite deformations.
