Fiber metal laminates (FMLs) are high-performance hybrid structures based on alternating stacked arrangements of fiber-reinforced plastic (FRP) plies and metal alloy layers. In this paper, effect of some geometrical and material parameters on free vibrations of FML plates was studied. The first-order shear deformation theory (FSDT) as well as the Fourier series method was used to analytically solve the governing equations of the composite plate. The accuracy of the used method was verified by comparing the Rayleigh-Ritz analytical method and the ABAQUS finite element software (numerical) method. The results indicated that some of the important parameters like sequence of metal layers, aspect ratio (a/b) of plate and orientation of composite fibers were important factors affecting free vibration of the FMLs.
