Temperature during thermoforming significantly affects the forming process. Based on the thermo-mechanical coupling, a rigid visco-plastic finite element method is used in this paper to analyze the multiphysics and deformation laws of bell-shaped multi-process thermoforming. The results show that multi-process thermoforming finite element simulation of forming temperature has guidance and reference
