| Abstract: | because of the limitation of conventional axial symmetric and plane symmetric shaped charge, based on the classical Birkhoff theory and some simulated results, an annular cutting is examined in theory, and an ideal designing method is presented in this paper. Parameters influencing the effectiveness of shaped charge are discussed, The relative of the liner thickness, the angle, the charge radius is obtained. It can be useful to the design of annular cutting. |
