We conducted perforation experiments with 26.3-mm-thick, 6061-T651 aluminum plates and 12.9-mm-diameter, 88.9-mm-long, 4340 R{sub c} = 44, ogive-nose steel rods. For normal and 30-degree oblique impacts with striking velocities between 280 and 860m/s, we showed good agreement between residual velocity data and predictions from a closed form perforation equation. We measured residual velocities and displayed the perforation process with x-ray photographs. These photographs showed clearly the time-resolved projectile kinematics and permanent deformations.
