Penetrating and Damaging Effects of a Split Kinetic EnergyProjectile on Concrete Targets

In this paper, to explore the mechanism of advanced active earth-penetrating weapons, we propose a split kinetic energy projectile.The target penetrating processes of the split projectile were analyzed using the finite element method, and the calculation model was verified by comparing the results obtained from simulation and experiment.Moreover, the crushing characteristics of the concrete target were evaluated adopting the fractal geometry method.The results show that the split kinetic energy projectile can significantly improve the lateral damage capability when applied to rock or soil targets.Besides, the cumulative mass distribution of the plain concrete fragments is fairly consistent with the statistical fractal rules, indicating that the fractal dimension is a good parameter to describe the projectile's crushing characteristics.
