Computation method of shaped-charge jet penetrating concrete targets

Concrete is widely used in military and civil buildings with its special features, and many ground and underground works (for example, airdrome track, underground bunker, etc) are multi-layer concrete constructions. Using shaped-charge jet to penetrate multi-layer concrete targets is a common method, however, the thickness of each layer target is generally limited and the influence of targets boundary effect to the penetration must be thought of. Because it is very difficult to calculate penetrating depths and penetrating radius by common ways, a new engineering calculation method - Superimposition Method is introduced In this paper and the rough calculation about penetration depths can be found by it, which provides some reference basis for solving some actual engineering problems.
