Abstract

Abstract

The concept, application back ground and generation of strong detonation were briefly introduced. The JWLT equation of state was embeded in one dimensional hydrodynamic program. The experimental model of strong detonation was simulated with the program. The pressure and density distribution of production of explosive were drew, and the existence of strong detonation was shown. The velocity curves of second flyer free surface are in good agreement with the experimental results. This work may afford validation and reference for studying the strong detonation.
