Fracture of Kinetic Energy Rods Subject to Oblique Impact

The scope of this paper is to examine the ability of CTH, an Eulerian shock physics code, to detect stress concentrations at buttress groove roots and to predict rod fracture due to stress concentrations under simulated experimental conditions. Computational studies were performed using the ARL6A-T rod. Simulations were run using forward ballistics (rod in motion) and reverse ballistics (target in motion). The reverse ballistics simulations yielded results that were qualitatively more accurate
