| 摘 要： | 基于空间轴对称热弹性理论和最大剪应力强度理论，建立了脉冲激光辐照下薄片发生反冲塞破坏的一个理论模型，导出了薄片反冲塞的激光功率密度阈值条件。以空间均匀分布的ms级脉冲激光辐照铜薄片为例进行了理论计算和数值模拟，给出了激光功率密度阈值随薄片厚度线性增加的关系，得到了与文献中相应实验结果基本一致的薄片反冲塞破坏的激光功率密度阈值数据。

| Abstract: | Based on the Principle of Maximum Shearing-Stress, a theoretical model is developed for the reverse-plugging of a thin plate under irradiation of long pulsed laser. The formula of the laser density threshold for the reverse-plugging is deduced. As an example, the reverse-plugging of a Cu thin plate irradiated by ms-degree long pulsed laser is calculated both analytically and numerically, and the laser density threshold and the temperature data are obtained. The analytical, numerical and experimental results are in good agreement with one another. |
