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

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.
