Abstract
MESMs will be triggered into reactions in the case of energy supplied by the passage of sufficiently strong shock waves. In order to analyze the shock-induced chemical reaction for MESMs, this chapter presents a theoretical model to be used to calculate the Hugoniot data of shock induced chemical reactions of MESMs. The mechanism of shock reactions of MESMs is firstly introduced, including the classification of MESMs and the two categories of shock reactions. The Arrhenius reaction rate and Avrami-Erofeev kinetic models that are controlled by shock temperature are used to calculate the extent of reaction of MESMs. The influence of parameters of the reaction kinetics model on the reaction efficiency was also discussed. The specific volume, shock pressure, and temperature rise were updated considering the chemical reaction. Theoretical calculations are compared with the experimental results on shock compression of Fe2O3/Al, Al/Ni, and Ti/Ni granular mixtures.
