| 摘要: |
| 用弹塑性模型和流体模型，对强激光脉冲辐照铝靶引起层裂分别进行了计算，并作了比较。对弹塑性模型用不同的断裂判据进行了计算，断裂判据不同对结果的影响也作了比较。当固定激光功率密度与波形时，给出不产生层裂的厚度阈值。 |

| A Calculation Analysis of the Spall Induced by Intense Laser Pulse in Aluminum Target |
| Bei Xinyuan, Zhang Zhijie |
| Abstract: |
| The spall phenomena induced by intense laser radiation pulse in aluminum target have been calculated with the elastic-plastic model
and the hydrodynamic mode1. The results are compared. For the elastic-plastic model the ca1culation is performed by using different fracture criterions，and the effects of them on the results are also compared. In this paper the thresholds of thickness at which the spa1ling is just prevented are obtained in the case when the laser power density and the wave shape are fixed. |
