Penetration Analysis of a Rod-Shaped Projectile in Semi-Infinite Target

When analyzing the penetration of a rod-shaped projectile in semi-infinite target, the velocity gradient of the shaped charge jet is taken into account. The jet is divided into a series of segments, and the variations of the length and diameter of each jet segment are calculated at the moment of impacting on the target. Through the Bernoulli equation, linear approximations of velocity and diameter of the jet, and static method, the relationship between penetration depth and hole diameter in the target and impacting jet is obtained. Moreover, the simulated results are in quite good agreement with the experimental data.
