Fundamental equations based on the linear-thermovisco - elastic theory were established to determine the residual stress and deformation due to cooling in a multilayer laminated beam. The transient thermal stress distribution and deformation in an epoxy resin/aluminum alloy laminated beam during the cooling process was calculated using these fundamental equations, then these beams were actually subjected to the cooling process. The experimentally obtained values revealed a high level of correlation with values theoretically calculated by the thermoviscoelastic analysis. The results demonstrate the necessity of thermoviscoelastic analysis for obtaining the residual stress and deformation due to cooling of multi-layer laminated beams made of thermosetting resin and elastic material.
