Shock Compression and Chemical Reaction of Multifunctional Energetic Structural Materials provides an exhaustive overview of the mechanics, kinetics and physio-chemical behavior caused by shock-induced reaction and shock compression on multifunctional energetic structural materials (MESMs). The book covers foundational knowledge on shock waves and Equation of State (EOS), shock parameters, reaction kinetics, impedance matching, and more. In addition, it looks at more advanced subjects such as experimental analysis methods, numerical modeling techniques (from quasi-static to high-strain rates, including void collapse models), how EOS changes when reaction and detonation are involved, and more.
Final chapters cover how to obtain EOS curves from experiments and various testing methods and numerical models for non-reactive porous solids and particulate composites, including 1-D reactive flow models. Flyer plate impact experiments are also discussed, as are the applications of hydrocodes and Lagrangian-framework-based methods.
