Abstract: (1731 Views)
In this research the analytic method of Green's function and the numerical method of finite difference were combined to investigate the laser-material thermal interaction. A new semi-analytic method is introduced and used for simulation of interaction. With this method, it is possible to encounter surface radiation in the Green's function, as well as increase the accuracy and speed of the calculations. Based on presented theory and using the programming language C a code was written. The thermal interaction of the laser with Al (7075) is simulated. An experimental setup was provided for empirical assessment. Simulation results were compared with experiment results. Good agreement between simulation and experiment results indicate the accuracy of the method and written code based on it. The computational speed is also high compared to similar numerical software.
