Abstract

Abstract

A 2-D finite element code was adopted to compute several one-dimensional overdriven shock states of flyer plates impacting on PBX-9501 explosive with the JWL(Tang) equation of state. And the velocities of the flyer plates driven by the explosive were presented. The results of numerical simulation agree well with that of the experiment by Fritz J N, et al. The new equation of state with correction and the adapted code are verified.
