Abstract
We conducted three sets of depth-of-penetration experiments with limestone targets and 3.0 caliber-radius-head (CRH), ogive-nose steel rod projectiles. The ogive-nose rod projectiles with length-to-diameter ratios of ten were machined from 4340Rc45 and Aer Met 100Rc53 steel, round stock and had diameters and masses of 7.1 mm, 0.020 kg; 12.7 mm, 0.117 kg; and 25.4 mm, 0.931 kg. Powder guns or a two-stage, light-gas gun launched the projectiles at normal impacts to striking velocities between 0.4 and 1.9 km/s. In addition, we present an analytical penetration equation that described the target resistance by its density and a strength parameter determined from depth of penetration versus striking velocity data.
