A Numerical Study of Projectile Impact on Explosives

Abstract

HELP code is employed to study the impact to a projectile on heavily confined, inert, solid explosive Comp B3. Temperature rise due to shock compression and plastic deformation, in both the explosive and the metal confinement, is estimated. In addition, the effect of variation of the imapct parameters, such as projectile diameter, projectile velocity and confinement thickness on the rise in temperature is studied. It is concluded that usually shock is a dominant mechanism responsible for significant heating of the explosive. However, in certain situations, plastic deformations may lead to violent reaction in confined explosives.
