Improved Modeling of Electrically Exploded Fuse Opening Switches in Flux Compression Generator Experiments

Abstract

In previously reported computational studies of fuse opening switches and other exploding metallic foils, apparent inaccuracies in the constitutive relations for the fuse material limited the accuracy of the modeling. In this paper, we use recently developed constitutive property models to re-examine experiments that used flux compression generators to deliver 25-35 MA to a copper fuse. Based upon this preliminary study, it is difficult to conclude that the newly developed models offer substantial improvement. For some considerations, models developed more than 15 years ago remain the most accurate.
