Shock Behaviors of Plastic-Bonded Explosives with Interconnected Meso-Scale Networks of Various-Sized Energetic Crystals

Abstract

The overarching goal of this proposal is to establish novel design and manufacturing techniques for creating plastic-bonded explosives (PBXs) with precisely controlled microstructural patterns that can yield targeted sensitivity properties. The central idea is to engineer meso-scale interconnected networks of crystals within PBXs using combinations of particle sizes to induce designed material dynamics upon shock loading that can trigger specific patterns of hotspots (i.e., localized regions of elevated temperature). The scientific objective of this proposal is therefore to elucidate and quantify the material dynamics induced by the meso-scale interconnected networks of various-sized crystals under shock loading conditions.
