Numerical Simulation of Semi-Infinite Target Penetration by Continuous and Segmented Rods

Abstract

This report presents results of a numerical study of continuous and segmented rod impacts into semi-infinite steel targets at velocities of 1.5-4 km/s. Variations in segment spacing and number of segments comprising a segmented rod were considered in addition to striking velocity variations. It is found that below 2 km/s, there is no advantage (in terms of penetration) in using segmented rods over continuous rods. However, for striking velocities exceeding 2 km/s, segmented rods show improved penetration with proper adjustment of segment number and spacing. (aw)
