Penetration and perforation of ceramic/aluminum composite targets by high-speed tungsten alloy sphere

Ballistic properties of tungsten alloy spheres penetrating normally through ceramic/aluminum composite targets are investigated and analyzed. The mode of deformation and failure of the tungsten sphere and the target during penetration is explored. The ballistic limiting velocity of the target with different area density is measured. The process and mechanism with which a tungsten sphere penetrates ceramic/aluminum and steel armor are studied and analyzed. It is useful in the design of warhead and light-armors.
