摘要：

Creation of a reliable system of protection for barriers requires investigation of various means for opposing high-velocity elongated projectiles. This paper considers the interaction of projectiles with explosively oppositely flung systems of smooth composite (layers of a tungsten alloy and ceramics) and finned plates as well as with different combinations of rods made from a number of materials. At the moment of contact the rods and the projectile form a cross-shaped configuration. The deformation and destruction of the projectile reduce its penetrability and the possibility of piercing the casing of the object being protected. The paper considers the collision of the formed fragments of rods with protective barriers. © 2017 by Begell House, Inc.
