The long-term viscoelastic behaviors of composite multilayer plates have been accurately analyzed based on Efficient Higher-Order Theory (EHOPT). The time-dependent relaxation modulus of viscoelastic materials has form of Prony series which determined from experimental data. The constitutive equation for linear viscoelastic materials as Boltzmann superposition integral equation is simplified by convolution theorem of Laplace transform to avoid direct integration as well as to improve both accuracy and computational efficiency. Because of EHOPT’s advantage, the both global and local behaviors of laminated plate are predicted accurately. The numerical results for graphite/epoxy GY70/339 composite material are analyzed and compared with the solution of elastic one.
