中文摘要：

采用动力学有限元分析软件ANSYS／LS-DYNA对316L不锈钢靶板在脉宽为纳秒量级的强激光诱导的冲击波作用下的变形速度进行了数值模拟，建立了适用于高压高应变率条件下的有限元模型，并将数值模拟得到的速度曲线与前人实验结果进行了比较，验证了模型的正确性。此外，靶板的变形速度随冲击波压强的增加而增大，随靶板厚度的增加而减小。模拟结果对研究激光冲击成形、靶板层裂以及侵彻等过程具有参考意义。

英文摘要：

The dynamic finite element software ANSYS/LS-DYNA is used to numerically simulate the deformation velocity of 316L stainless steel target after the influence of shock waves induced by intense lasers with pulse duration of nanosecond scale, and a finite element model suitable under the high pressure and high strain rate conditions is established. The velocity curves obtained from the numerical simulation are compared with the previous experimental results and the validity of the above model is confirmed. In addition, the deformation velocity increases with the increase of the shock wave pressure and decreases with the increase of the target plate thickness. These simulation results provide a reference for the study of those processes, such as laser shock forming, spallation and penetration.
