摘要: 用有限元法模拟了连续激光辐照受载金属所产生的软化效应。建立了计算软化效应的二维有限元数值模型。得到了软化效应与预载荷、激光功率密度的依赖关系。结果表明,激光产生的软化效应会大大降低金属材料的屈服阈值,且材料的软化程度与预载荷及激光功率密度有关。

Abstract: The termal degradation effects in the preloaded metal thin plate irradiated by CW laser beam are calculated with the finite element method. A two dimensional mode to calculate the degradation effects induced by CW laser beam is set up. The yielded degradation thresholds and time as well as the dependence of the degradation threshold and time on the laser power densities and the preloads are given.
