Meso-scale calculations of energy localization and initiation in energetic material microstructures must capture the deformation and collapse of pores and high-temperature …
The thermo-mechanical response of shock-initiated energetic materials (EMs) is highly influenced by their microstructures, presenting an opportunity to engineer EM …
Head-to-head comparisons are made between calculations and experimental data on shock- driven pore collapse in the transparent material, poly (methyl methacrylate)(PMMA) …
Accurate simulations of the shock response of heterogeneous energetic (HE) materials require closure models, which account for energy localization in the micro-structure. In a …
The sensitivity of an energetic material is strongly influenced by its microstructure. This work distinguishes the roles played by the microstructure (ie, the meso-scale) in the macro-scale …
In porous solid energetic materials, the mechanical processing technique (eg casting, pressing) creates defects such as voids, cracks, interfaces, and inclusions; these defects in …
