ASSESSMENT OF MECHANICALLY INDUCED DAMAGE IN SOLID ENERGETIC MATERIALS
RÉSUMÉ
This paper describes the use of the shotgun/friability test as a means to determine the level of damage induced in a series of energetic materials. Five propellants and three explosives have been evaluated and the contribution of burning rates, loading density, and binder type on pressurization rates and damage levels have been examined. The changes in burn area are best used in the determination of damage, while the use of maximum dp/dt is best for the estimation of reaction violence. Within a family of propellants, the higher the burning rate, the higher the maximum dp/dt. The cast-cured explosive samples demonstrated lower damage levels than the melt-cast explosive sample examined in this report; however, the damaged melt-cast sample was more difficult to ignite in the closed bomb.
