Novel semi-analytical solution for thermoelastic problem of composite laminated plate

Abstract

Abstract: To simplify the theoretical form of semi-analytical solution for Hamilton canonical equation and improve computational efficiency, a novel semi-analytical solution for solving thermoelastic problem of laminated plate is proposed. Based on minimum potential energy principle and modified H-R variational principle,a novel semianalytical mixed element is developed by combining thermoelasticity displacement element and Hamilton semianalytical mixed element. The proposed mixed element combines the advantages of displacement method and semi-analytical solution of Hamilton canonical equation, simplifying the solving process. Finally, a numerical example is employed to verify the accuracy and superiority of the proposed method for analyzing thermoelastic problem of composite laminated plate.

Key words: thermoelasticity, Hamilton canonical equation, semi-analytical solution, displacement method, composite, laminated plate
