| Abstract: | This paper takes advantage of 3D explicit finite element method to simulate the process of linear shapedcharge jet formation. The distributing characteristics of varied parameters, such as velocity and density, in the shapedcharge jet and slug are analyzed. The break-up phenomena in the jet and slug during their flight process are alsodiscussed. It is helpful to theory investigation of linear shaped charge. |
