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.
