Abstract:

This project uses molecular dynamics simulations to study the short - time chemistry and physics of detonating solids. A variety of condensed phase systems are studied ranging from one-dimensional chains to complex molecular solids. This research first requires the development of potentials capable of realistically modeling shock-induced chemical reactions in energetic molecular solids. Molecular dynamics simulations using these potentials are then carried out to study the role of molecular-scale chemistry in the initiation and propagation of solid-state detonations. This research addresses a number of fundamental issues including i whether concerted chemical reactions at or near the shock front sustain a detonation ii whether parallels can be drawn between gas-phase reactions and detonations, and iii whether molecular scale dynamics can provide insight into making safer explosives. js
