| Abstract: | The software of LS-DYNA3D is applied to numerical simulation of the formation process of rod shaped projectile. The influencing factors such as outside curvature radius of liner, thickness of casing and outer explosive on the formation of rod shaped projectile is studied. The correlations among all the structural parameters for the formation of an ideal rod shaped projectile are determined. The influence of casing material on formation of projectile is investigated. Moreover,the difference of condition between the use of steel casing and aluminum casing in forming an ideal rod shaped projectile is compared and discussed. The simulation results can be applied to design the rod shaped projectile warhead with light casing. |
