Abstract: The coupling computation method which combines numerical solution and analytical one is used in simulating the annular jet formation and penetration into the target. The actual results indicate that this is the method is of having better computational precision and saving lots of computational time. It can be applied in the design of shaped charge.

Key words: annular jet, W shaped charge, MOCL, numerical simulation
