摘　　要：关于混凝土侵彻的研究一直是一个很活跃的领域,但由于整个侵彻过程时间极短,实验研究很难对侵彻过程进行全面准确的分析。文中利用LS-DYNA 3D有限元程序对弹丸在不同速率和着角下侵彻混凝土靶进行了三维数值模拟,得到了侵彻的整个图像和主要数据,分析了速率和着角与侵彻深度及破坏情况之间的关系。研究表明:速率和着角对侵彻深度具有重要影响。The research on-projectile penetrating into concrete target is always a realm. But the time of the whole penetration process is very short, which makes researchers difficult to give the general and accurate analysis according to experiment. In the paper, projectile penetrating into concrete target was simulated under the different velocity and angle of incidence, the whole picture of the penetration and main data was gained. According to research, velocity and angle of incidence plays an important part in penetration depth.
