Dynamic response of a projectile perforating multi-plate concrete targets

By means of the ultimate-density theory, the dynamic cavity-expansion theory and the stress-wave theory, the dynamic responses especially the deceleration curves of a projectile perforating multi-plates concrete targets are analyzed and calculated, the principles of scabbing on the rear surface of target plate are analyzed and illustrated. To verify the theoretical model, the deceleration tests are conducted for perforation of a projectile against multi-plates concrete targets by use of on-board recording system. Model predictions show good agreement with measurements from the tests.
