【 摘 要 】
As an important basis for the laser processing industry, the essence of laser irradiation process on metal materials is the interaction between laser and metal materials, involving multidisciplinary cross-coupling of optics, thermals and mechanics. Due to the great influence of the thermal effect on materials, the study of modern laser technology is generally believed that the energy of laser is mainly converted into heat. Based on the finite element software ANSYS, the thermal effects such as temperature field distribution and temperature rise process of metal materials under laser irradiation can be numerically simulated. In this paper, the laser irradiation of metal target plate is taken as the background, and the two laser energy loading forms of Heat Fluxes (HFLUX) and Heat Generation Rates (HGEN) are studied to find a more realistic numerical simulation method, which provides a reference for the numerical simulation of the thermal effect of laser irradiated metal materials.
