- W4313331856 abstract "Concrete piles are a common obstacle in an antilanding obstacle field. To research the damage ability of concrete piles with different shaped charges, penetration tests of concrete piles with different standoff distances (SODs) were carried out with explosively formed projectiles (EFPs) and jetting projectile charges (JPCs). The pressure was measured at different positions inside the concrete piles during the penetration process, and the failure mechanism and damage characteristics of the concrete piles were analyzed. The penetration velocity of the JPC was measured by placing reticular targets inside the concrete pile. The results show that the damage ability of JPCs to concrete piles is stronger than that of EFPs. When the SOD is in the range of 20∼50 cm, an EFP causes slight damage to a concrete pile. With the increase in SOD, the penetration capacity of JPCs increases, but the damage ability of JPCs decreases. When the SOD is 15 cm, a JPC causes severe damage to a concrete pile, and when the SOD is in the range of 20∼40 cm, a JPC causes moderate damage. When attacking targets with obvious side boundary effects, such as concrete piles, the SOD that results in the strongest damage is not the SOD that results in the strongest penetration ability." @default.
