Some aspects of nonideal detonation in composite explosives

A theoretical treatment is formulated for steady-state planar detonation waves in composite explosives such as Amatex 20. This treatment provides a more definitve and realistic description of detonation in such explosives, and extends the classical Zeldovich-von Neumann-Doering model of ideal detonation into a propotype model for nonideal detonation. Incomplete decomposition of the slowest reacting component, and incomplete attainment of chemical equilibrium among the detonation products from the different explosive components were assumed to be the kinetic processes responsible for nonideal behavior. The constitutive relationship for the shocked reacting explosive was constructed with different equations of state for the explosives and their products and enough reaction coordinates to account for this type of nonideality. Detonation parameters and Lagrange particle velocity histories were calculated for nonideal detonation waves in an explosive modeling Amatex 20.
