We conducted acceleration-time measurement of penetration experiments in targets with 100 mm diameter, 4.0 caliber-radius-head, 25 kg projectiles. The 3 m×3 m×3m and 2 m×2 m×2m concrete targets had an nominal unconfined compressive strength of 35 MPa and density 2 450 kg/m3. Projectiles were designed to contain a single-channel acceleration data recorder, so we recorded accelerations in the bore of the gun and accelerations during the penetration event. A 100 mm diameter powder gun launched the 25 kg projectiles to striking velocities between 310 and 632 m/s. We compared the measured penetration depths and acceleration-time data with the calculated results using Forrestal formula. The calculated results are in good agreement with rigid-body acceleration measurements for the rise times and peak plateau responses. The acceleration-time data of projectiles can be helpful for devising armour-piercing projectile and defense engineering.
