Penetration depth of high-velocity projectiles for geomaterials through an empirical equation

When designing projectiles, the prediction of the penetration depth is an important problem. In this paper, a fast penetration analysis method using an empirical equation suggested by Young is presented. The proposed method was validated by predicting the penetration depth for soil, rock, and concrete targets and comparing the results with the experimental data of previous works. The proposed method was verified by the comparison of the penetration depth and residual velocity values obtained in the experiment and the results of the empirical equation. The errors of the residual velocity were 0.92 % and 1.91 %, and for the penetration depth, they were 9.31 % and 4.62 %. The proposed method predicts the penetration behavior of the projectile accurately and efficiently.
