Materials used: The materials used in this study are Structural Steel . The properties, including thermal conductivity, heat capacity at constant pressure, and density, were defined in the simulation for accurate modeling.
3D Temperature Distribution
3D temperature distribution of structural steel at t = 0.033333s. The highest temperatures occur at the top surface where the laser interacts, while the bottom remains cooler due to thermal conduction. The gradient illustrates the heat transfer path and cooling behavior.
Surface Temperature Distribution Near Laser Path
Surface temperature distribution of the material after laser heating. The color gradient indicates variations in temperature across the surface, showing regions of high thermal exposure
