The simulation of the final dimension in the glass pressing process is presented in this paper, in which the part contraction and mold deformation are considered as important factors. A thermorheologically simple thermoviscoelastic material model is used to calculate the residual stress. The model for the analysis of contraction is proposed based on the theory of shells, as an assembly of flat elements. The numerical model for the mold deformation is based on a three‐dimensional thermoelastic boundary element formulation. Finally, an application example of the picture tube panel is used to verify the presented models and simulation methods.
