Abstract

Abstract : The cover picture shows the experimental and simulation results of bore‐center annular shaped charge (BCASC) penetration into single‐layer and double‐layer concrete targets. For all the cases, the diameters of the rear crater are larger than that of the front ones. The penetration depth of optimized BCASC into concrete exceeds 3.0 times of the charge diameter ( D ). Hole diameters of penetrating tunnels are larger than the charge diameter. For the single‐layer concrete target, the hole diameter of the penetrating tunnel is 2.26 D . And, for the double‐layer concrete target, the hole diameters of the first and second layers are 1.41 D and 1.33 D, respectively. More details can be found in the Full Paper by Michael S. Gruhne, Marcus Lommel, Maximilian H. H. Wurzenberger, Norbert Szimhardt, Thomas M. Klapçtke, and Jçrg Stierstorfer on page 1628 ff.
