A simplified equation, designed to obtain inter-layer residual stress arising when thermal load was provided to a viscoelastic laminate beam consisting of various materials, was proposed, and reasonableness of the equation was examined through comparison with exact solution based on thermal viscoelastic analysis. The proposed simplified equation is composed of the glass transition temperature, the rubber transition temperature, the elastic coefficient, and the linear expansion coefficient of the component material. Based on this composition, it has been clarified that the equation allows calculation of inter-layer residual stress in laminated beams. Because the simplified solution of the inter-layer residual stress that is generated in viscoelastic laminate beams is well consistent with the precise solution derived from the basic thermal viscoelastic formula, the rationality and efficiency of the simplified solution have been revealed.
