A simplified evaluation equation that handily predicts the warp deformation behavior arising when the thermal load was provided to a viscoelastic laminated beam consisted of epoxy resin and steel material was proposed, and reasonableness of the equation was verified through comparison with not only exact solution based on thermal linear viscoelastic theory but experimental values. The proposed simplified evaluation equation is composed of the glass transition temperature, the rubber transition temperature, the elastic modulus and the linear thermal expansion coefficient of the component material. It this study, it was clarified that the warp deformation behavior of the viscoelastic laminated beam could be predicted handily by using proposed simplified evaluation equation which was divided elastic modulus into three regions such as glassy state, leathery state and rubbery state.
