摘要 从电子-声子相互作用的双曲型两步热传导模型出发,考虑到金属体内晶格对热传导的影响,采用有限元法,直接在时间域中求解了金属薄膜内受短脉冲激光加热的二维热机耦合问题,避免了以往因电子-声子能量方程之间的耦合关系给二维热响应问题解析求解带来的困难,提高了用数值反变换工作时计算的精度,减少了工作量,得到了金属薄膜内二维热机耦合问题的温度、位移和应力的变化规律。 Based on the hyperbolic two-step thermal conduction model,the two dimensional thermo-mechanical coupling of metal thin film under short pulse laser heating is investigated with finite element method.The equations are solved directly in time domain to overcome the coupled difficulties and cut down computational task with higher accuracy.The temperature,displacement and stress fields in the thin film are obtained and shown graphically.
