靶材热烧蚀效应的有限元分析方法

Method of Finite Element Analysis of Thermal Ablating Effect on Target Material

强激光辐照靶材引起热烧蚀效应,单元死活技术是Ansys或M arc通用软件中处理热烧蚀过程常用的一种技术,它允许用户在计算分析过程中根据需要随时增加或删除单元.本文采用单元的死活技术和激光辐照引起的热流加载控制相结合,通过一个算例来模拟靶材激光热烧蚀效应.

The target material irradiated by intense laser will be ablated. The deactivated-or-activated element technique is usually used to deal with thermal ablation in common software such as Ansys or Marc, which allows elements to be added or deleted as often as needed in calculating and analyzing process. The deactivated-or-activated element technique and thermal load arising from laser irradiation are adopted in an example to simulate laser thermal ablating effect on target material.
