Abstract:

An experimental and analytical investigation was conducted to study the physical and chemical processes governing the ignition and release of energy under low amplitude, accidently applied stimuli. To determine the mechanisms responsible for initiation of detonation in low-speed impact a two-dimensional tensor code has been developed. The code is applied to calculations of the mechanical response of solid composite and double base propellant materials in unconfined impact against a rigid surface. Computations were also carried out for TNT. Estimates were made of the transient temperature field in these materials resulting from the dissipation of the mechanical energy of impact. Impact experiments on solid propellants and on inert simulants were also carried out.
