Penetration of 7075-T651 aluminum targets with ogival-nose rods

Abstract We developed analytical models that predicted forces and penetration depths for long, rigid rods with ogival noses and rate-independent, strain-hardening targets. To verify our models, we conducted terminal-ballistic experiments with 7.1 mm diameter, 0.025 kg, 3.0 caliber-radius-head, ogival-nose rods and 152 mm diameter, 7075-T651 aluminum cylindrical targets. The model predicted penetration depths in good agreement with the data for impact velocities between 370 and 1260 m s−1.
