“…The most prolific theory that describes the bulk response of metals undergoing electrical explosion is one that Tucker and Toth [3] use to parameterize a resistivity curve for particular metals. This theory, described in Figure 1, describes the resistivity of a metal, as functions of its phase, and implies that there are discrete points in time where the metal changes phase on the bulk scale.…”

Abstract. During the electrical explosion of bridge-wires and bridge-foils, the metal bridge undergoes rapid resistive-heating. The metal is rapidly expanded through solid, liquid, vapour and plasma phases. This study uses ALEGRA MHD, a Sandia National Laboratory magneto-hydrocode, to predict the formation of these metallic phases during the explosion process and determine the effects of surface heterogeneities on the spatial distribution of these phases. The simulations are compared against x-ray phase contrast radiographs of electrically exploded bridge-foils. From comparison of these data, it is evident that the meso-structure of the metallic foil dominates the explosion process and is something that should be controlled during the manufacturing processes for detonator designs.

“…Burnt tire-of 20&so0 m at currents of 1-4 kA were observed, and the burst actions were determined, As Fig. 1 indicates, burnt actions from approximately 1.5 to 2.5 times the value repotied by Tucker and Toth [4] were observed, and CONFUSE computations were in reaaonabln agreement with the observations.…”

In order to explore optimal plate spacing, based on the principle analysis of passive electromagnetic armor system, and combined with the mathematical model of the time of pulse current acting on shaped charge jet is established based on the virtual origin concept, the effect which the armor plate spacing had on the shaped charge jet acting time is analyzed. Combined with the specific action model, the numerical value of specific action variation rules along with passive electromagnetic armor plate spacing are analyzed by Matlab. The results show that: there is a most optimal choice of armor plate spacing, which could make the peak value of shaped charge jet specific action reach to the maximum.
