Numerical simulation of transient temperature field on metal material induced by pulse laser irradiation

摘要: 为了研究脉冲激光辐照金属材料时温度场的变化,采用有限元模拟软件对激光辐照材料的过程进行了模拟。得到了激光辐照过程中,材料表层及内部的瞬态温度场的变化情况。结果表明,在脉冲激光辐照金属材料过程中,激光热作用时间很短,热影响区仅限于激光光斑作用区域的材料表层。

Abstract: In order to study the temperature field on metal material induced by pulse laser irradiation,the finite element simulation software was introduced to simulate the process of laser irradiation.The material surface and internal changes of the transient temperature field was obtained.The results show that the time of hot effect is very short in the laser irradiation process,and the heat affected zone is limited to material surface of laser irradiation area.
