| 摘 要： | 高速破片撞击装甲钢的层裂问题，应考虑侧向稀疏波效应的影响．应用二维MCA方法模拟破片高速撞击装甲钢，以元胞速度场直观地描述这种侧向稀疏效应．模拟得到不同速度撞击下，靶板背面的破坏形态和层裂片形貌、分布及飞散速度，符合实际结果．

| Abstract: | The effect of lateral release wave must be considered for spallation of armor target impacted by high speed fragment.The 2D-MCA method is used for the simulation in this article,and the effect of lateral release wave is described directly on velocity-field of cells.From the simulation,the damage pattern on back surface of target and the shape,distribution,and velocity of spall are got at different velocity of impact which agree well with actual result. |
