On the Explicit Determination of the Chapman-Jouguet Parameters for an Explosive Compound
Abstract
This work re-examines earlier development and current advances of the shock Hugoniots in anticipation of developing an explicit solution to determine the Chapman-Jouguet (C-J) parameters for an explosive compound. A new and simple equation for the C-J specific density was obtained as a function of three measureable parameters: initial density, detonation velocity and the heat of detonation. For the ratio of specific heats, , an explicit expression as a function of the C-J parameters was obtained. The relations were tested for the very well characterize explosives PETN, HMX, RDX, TATB, TNT and the calculated values obtained for the C-J parameters and gamma, compared very well with published experimental values. The equations were then applied to a broad range of explosives types regardless of their heterogeneity or their physical state and the C-J parameters obtained compared very well with published values.
