Theoretical characterization of ballistic performance of armor ceramics

With Tate penetration theory and cavity expansion theory, the kinematic parameters of the long rod penetration and the ceramics differential efficiency factor DEF are expressed as functions of the materials properties. In this way the experimental index of the ballistic performance of armor ceramics is theoretically expressed and the key ceramic properties which have the most significant influences on ballistic performance are mathematically formulated. Calculation shows that this theoretical method can give a good ballistic performance estimate for ceramics against long-rod penetration.
