| 摘 要： | 为研究耦合系数随温度变化对短脉冲激光辐照金属材料产生的温度场分布的影响,基于双温耦合理论,建立了短脉冲激光辐照金属材料金加热过程的有限元求解模型.在同时考虑脉冲激光的空间、时间分布和多参数同时随温度变化的情况下,计算得到了短脉冲激光辐照金属材料金激励产生的温度场瞬态分布,比较了耦合系数随温度变化和不随温度变化两种情况下...

| Abstract: | Based on the two-temperature theory,a numerical model to solve the heating process at surface vicinity irradiated by ultrashort pulse laser is established to investigate the influence of temperature-dependent coupling of material on temperature field in metal Au irradiated by ultrashort pulse laser.Taking account of the temperature-dependent properties of material and the spatial and temporal shape of the laser pulse,the transient temperature fields by ultrashort pulse laser in metal(Au)is numerical simulat... |
