| Abstract: | Based on heat conduction theory,a finite element method is introduced to investigate the three-dimensional transient temperature fields in a moving plate irradiated by a laser beam.The laser beam is assumed to be with Gaussian distribution,and the plate is considered as infinite along the motion direction,while the width and the height are finite.Considering the thermal physical parameters depended on temperature,convection and radiation factors of the surfaces,and the motion of the plate,the temperature fi... |
