Investigation of the Influence of the Projectile Design on the Armor Penetration of Homogeneous Steel Barriers

Abstract

The article discusses the results of mathematical modeling for the penetration process of homogeneous steel barrier by armor-piercing discarding sabot projectile based on the results of modeling the internal and external ballistics. Based on elastic-plastic material model the problem is solved for penetration of the projectile into the target. Parametric studies have shown that for a nominal charge the final speed of the projectile when approaching the target and the depth of penetration of a steel barrier are non-monotonic, depending on the weight of the active part of the projectile and, respectively, on the diameter of the armor-piercing core.
