Modeling a Material's Instantaneous Velocity during Acceleration Driven by a Detonation's Gas-Push

摘要

Analysis of cylinder test data reveals that an explosive's gas-dynamic-driven acceleration of a boundary material from its initial free-surface velocity up to the final steady-state velocity can be described by an equation derived by fitting data for twenty explosives. The time derivative of this velocity equation can represent pressure as well as acceleration with results comparing favorably to Jones-Wilkins-Lee equation-of-state model calculations performed using published parameters.
