| 目的 研究钢弹冲击钢板的动力学响应。方法 采用ABAQUS/Explicit显式有限元分析软件， 基于SPH-FEM耦合方法和常规FEM方法对钢弹冲击钢板进行数值模拟， 对比两种方法得到的结果。结果 用这两种方法模拟得到的钢板Mises应力分布、 钢弹速度随时间变化规律及剩余速度基本一致。结论 SPH-FEM耦合方法用于模拟钢板冲击失效过程是可行的。 |

| Objective To research the impact interaction between a high-velocity projectile and a solid steel plate. Methods Coupled SPH-FEM and common FEM based on ABAQUS/Explicit software were used to numerically simulate the dynamic response and the results by the two methods were compared. Results The numerical results showed the changing patterns of Mises stress of plate and projectile velocity over time and the residual velocity by the two methods were basically identical. Conclusion The coupling method is feasible in simulating the failure process of steel plate impact. |
