Abstrakt: An electric explosion occurs when a micron-scale metal film, such as a copper film, is stimulated by a shorttime current pulse, while generating high temperature and high-pressure plasma. In this paper, the electric explosion process is divided into two stages, namely, the energy deposition stage and the quasi-isentropic expansion stage, and a dynamic EOS of the plasma considering the energy replenishment is established. On this basis, a flyer driven by plasma is studied numerically, and the pressure and the internal energy of plasma are obtained based on the simulation result which has been validated by experimental result. The influence of the backplane material on flyer velocity is analyzed. [ABSTRACT FROM AUTHOR]
