Mechanical Behavior of Energetic Materials at High Acceleration

Abstract

We have been studying the mechanical behavior of energetic materials during high acceleration by using an ultracentrifuge.1-5 Energetic materials are of significant interest for scientific and practical reasons in the extraction (mining) industry, structure demolition, space propulsion, and ordnance. In these applications the materials can be subjected to high acceleration, fluctuating and/or sustained. The nature of the fracture process of such materials under high acceleration is of particular interest, especially in ordnance and propulsion applications. For example, explosives in projectiles are subjected to setback forces as high as 50,000 g during the gun launch. These high setback forces can cause fracture and premature ignition of explosives.
