提出了一种简化的评估方程，可以方便地预测向由环氧树脂和钢组成的粘弹性层合梁提供热载荷时产生的翘曲变形行为，并通过与基于线性粘弹性理论的精确解和实验值的比较来验证该方程的有效性。所提出的简化评估方程由部件材料的玻璃化转变温度、橡胶转变温度、弹性模量和线性热膨胀系数组成。这项研究表明，利用所提出的将弹性模量分为玻璃态、皮革态和橡胶态三个区域的简化评价方程，可以方便地预测粘弹性层合梁的翘曲变形行为。
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 was proposed, and validity of the equation was verified through comparison with not only exact solution based on 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.
