Fundamental equations based on the linear-thermoviscoelastic theory were established to obtain the residual stress and deformation by cooling in a multi-layer laminated beam. The transient thermal stress distribution and deformation in an epoxy resin/Al alloy laminated beam during the cooling process were calculated using these fundamental equation, 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 nesessity of thermoviscoelastic analysis for obtaining the residual stress and deformation by cooling of multi-layer laminated beams made of thermosetting resin.
