| 摘要: |
| 应用动力有限元与SPH相结合的方法对刚性动性弹丸高速侵彻混凝土靶进行了数值模拟分析，使用HJC本构建模型描述混凝土。计算结果与在φ57气体炮上所获得的实验数据基本吻合，并能再现侵彻过程中弹的运动及混凝土的飞散、应力波的传播等物理现象。计算结果说明这种新的算法及HJC本构模型用来描述混凝土的侵彻问题是可行和有效的。 |

| Abstract: |
| The combination of dynamic FEM and SPH method was applied to simulate the concrete target penetrated by high-velocity rigid projectile. The HJC constitutive model was applied to describe the behavior of concrete material. The numerical results are in good agreement with recent experimental results obtained from φ57 gas gun, and reproduce the details of the movement of projectile, the scattering of concrete, the propagation of stress wave in the target. The feasibility and validity of applying the newly obtained method and HJC concrete model to simulate such problems as the high-velocity impact and penetration in concrete have been also proved. |
