A Unified Formula of Critical Penetration Velocity for Natural and Preformed Fragments Penetrating Into Steel Target

YU ZHENG, ZHONGWEI GUAN

Abstract


Using dimensional analysis method, a unified formula of ballistic limit velocity for natural fragments and preformed fragments penetrating into steel plate was established. The penetrations of natural fragments, spherical preformed fragments, cylindrical preformed fragments and cuboid preformed fragments into steel plates were studied by means of experiments. After the data processing of the test results, the empirical constants in the unified formula was obtained. The predicted results by use of the unified formula are in good agreement with the experimental results
