Abstract
This chapter investigates the vibration behaviour of harmonically excited simply-supported antisymmetric cross-ply and angle-ply laminated composite plates. The equations of motion are established based on the first-order shear deformation theory (FSDT) considering the effects of transverse shear deformation and rotary inertia. The steady-state responses at prescribed points on the plate are obtained from Navier’s solution technique analytically and are verified with numerical results based on finite element method. This theoretical approach with high accuracy is employed to investigate the effects of important structural parameters such as fibre orientations on vibration characteristics of the laminated composite plates. The results show that variations in lamination schemes effectively shift the resonant frequencies and change the corresponding resonance peak values. Increase of the fibre angle in antisymmetric angle-ply laminated composite plates may lead to the increase of resonant frequencies and decrease of the corresponding peak values. It is also shown that the vibration response of laminated composite plates at assigned excitation frequencies could be reduced by employing the optimised fibre orientations and stacking sequences of laminates.
