In order to analyze the influence of the detonation of the explosive to the penetration capability of the rod penetrator,the penetration process at different impact angle into plate covered by sandwich explosive are simulated by 3D finite element code(LS-DYNA),which are compared with the corresponding cases without explosive in the middle of two plates.

补充资料：侵彻力
侵彻力——亦称贯穿力，弹头钻入或穿透物体的能力。其大小主要决定于弹头质量、弹头活力的大小和物质的性质。通常以侵彻一定物体的深度来表示。
