Real-time Dynamics of Hot Spots in Microstructured Energetic Materials: Experiments and Simulations (Martin Schmidt)

Abstract

This project was a joint experimental/theoretical study of how microstructure affects energetic material initiation. Experiments were performed to study initiation by frictional rubbing, low velocity impact and high velocity impact on a variety of plastic-bonded explosives and single crystals. Theoretical modeling with multimillion atom simulations was used to explain the sensitivity of explosives to rubbing along different crystallographic axes and to explain the high temperatures observed at short times in shocked explosives.
