Abstract
The first aim of the study was to establish the temperature model of the eggshell by the finite element analysis software ANSYS and realize the eggshell temperature field based on the laser marking processing. The eggshell surface which created the meshing model, set the parameters with the ANSYS Parameter Design Language and simulated that the Gaussian distributed laser beam acted on the surface were established. In addition, marking characters made use of the CO 2 laser processing system on the brittle eggshell to analyze whether laser beams caused damage to the inner of the eggshell. According to the results of the comparison between the simulation by ANSYS and the experiment of laser marking, it is revealed that the heat-affected area by laser marking is similar to that of the simulation.
