Simulation Study on Anti-armor and Anti-personnel Composite Warhead

To enhance the warhead's end damage efficiency, this paper proposed an Anti-armor and Anti-personnel composite warhead. Aimed at a kind of warhead's structure dimensions. Using the LS_DYNA to study the Composite Warhead and the evaluation of the effect of the fragments. It is concluded that the ALE of many kinds of materials can be reasonably defined, and ALE algorithm can be defined, which can stabilize the interaction between fluid and solid; The interaction between erosion single automatic contact algorithm for multi component identification and track possible contact region, the algorithm can more real reflection of preformed fragment; fragment field can effectively kill radius in less than 41m effectives, and the radius in less than 16m light armored vehicle with damage efficiency.
