Abstract: Spherical-nose copper and tantalum rods with aspect ratios between 4.0 and 14.6 were gun launched against 91-cm-diameter and 91-cm-long concrete and simulant reinforced-concrete targets with velocities ranging from 0.15 ...

Abstract: Three-dimensional axisymmetric calculations of penetration of concrete targets have been conducted with the CALE (Arbitrary Lagrangian Eulerian) code. All the constitutive models studied accounted for the compressibility ...
