Modeling Solid State Detonation and Detonation with Designed Microstructure

Solid state detonation refers to nonclassical supersonic reactive wave phenomena in energetic materials that are not typically considered explosives. Reactive energetic materials include both metal/metal oxide and metal oxide/polymer systems with thermitic reaction. Like conventional solid explosives, the materials are manufactured composites with a well-defined microstructure. Ingredients include nano-engineered energetic materials with novel surface and reaction properties. The manufactured materials are still described by a continuum limit informed by the microstructural properties. We consider limit model formulations that include acoustic dispersion phenomena, intermaterial heat transfer and void effects and macroscopic ignition and extinction of steady traveling reactive waves, in a modeling framework that can aid the design of new materials.
