Abstract

Usually, it is difficult to obtain the equation of state (EOS) for the non-ideal explosive, such as emulsion explosives (EMXs), that is most used in an industrial explosive. The reason is that the detonation performance of a non-ideal explosive changes with the charge diameter and confinement a lot. In this research, as for the EMXs, it asked for the parameters of the JWL EOS obtained from the shape of an underwater shock wave (Underwater Explosion Test). Numerical calculation was performed about the detonation phenomenon of EMXs using this equation, and it compared with the experiment. The result was well in agreement between them.
