Abstract

Based on the design of a conventional Shrike warhead, an improved design of warhead is proposed, which combined the properties of a deformable warhead. The processes of explosive loading and fragments scattering are simulated by the finite element software LS-DYNA, the improved warhead and the conventional Shrike warhead are detonated in different initiating modes. According to data analysis, gains of fragment density and velocity on target have been achieved. Furthermore, the damage effectiveness of fragments against Patriot radar car has been estimated.
