Analysis on Damage Mode of Armor-piercing Projectile to Soil Target

Abstract Aiming at the reliability problem of armor-piercing projectile acting on soil target, experimental research and numerical simulation were carried out. The damage modes of armor-piercing projectile to soil target under different conditions were analyzed, and the characteristics of metal jet penetrating soil were studied. The results indicate that, there is a problem of reliability of fuse action in penetrating soil targets, if the soil strength is enough, the projectile will immediately explode and form metal jet when it touches the soil, if the soil strength is insufficient, the armor-piercing projectile will penetrate the soil, when the reaction force is enough, the armor-piercing projectile will explode and form metal jet, otherwise the armor-piercing projectile cannot explode, but the projectile will cause penetration damage to the soil.
