A Review of Recent Impact Sensitivity and Hot Spot Investigations

Abstract

During the past few years, at the Naval Surface Weapons Center, there has been an effort to understand the basic processes responsible for hot spot formation and ignition in solid propellants and explosives under impact loading conditions. This effort has resulted in the development of a new and versatile impact machine as well as a number of new instrumentation techniques. Shear and fracture have been identified as the most likely sources of hot spot generation. A fundamental understanding of the processes responsible for shear induced energy localization and potential hot spot generation has been obtained. This paper reviews these results as well as some recent developments in the related areas of explosive response and heating due to cracking.
