Based on the enhanced Reddy′s theory, the four-node quadrilateral plate element is proposed for the analysis of laminated composite plates subjected to thermal loads.Although transverse normal deformation is introduced in the proposed theory, the number of displacement variables is the same as that in the classical Reddy′s theory.The four-node quadrilateral plate element satisfies the requirement of C1 continuity conditions at adjacent elements.Numerical results show that the four-node quadrilateral plate element based on the enhanced Reddy′s theory can accurately analyze the thermal expansion problems of laminated composite plates, while the classical Reddy′s theory is less accurate.
