Damage Effects of Shaped Charges on Concrete Piles

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