Much time is required to numerically analyze the residual stress in a thermoviscoelastic body caused by the thermoviscoelastic behavior of materials through the cooling process by molding. Using constitutive equations simplified based on the characteristic of the thermoviscoelastic behavior of material through the cooling process, two simplified and efficient numerical methods are proposed to analyze the residual stress in plastics. The first method is applicable for the evaluation of the entire thermal stress history, while the second is suitable only for residual stress calculation. The validity of these methods are clarified by numerically analyzing the residual stress in an epoxy beam which has been cooled rapidly.
