Abstract - In
this study, free vibration analysis of Fiber Metal Laminated (FML) composite,
which is one of the frequently preferred materials in the automotive, aircraft
and aerospace industry due to its light weight, durability, good fatigue and
corrosion resistance, was performed numerically. The FMLs are hybrid structures
composed of fiber-reinforced polymer composites such as carbon/epoxy (CARALL),
glass/epoxy (GLARE), or aramid/epoxy (ARALL) with aluminum sheets. The
vibration parameters of the FML composite structures modeled by differential
quadrature (DQ) methods have been determined. The natural frequencies obtained
to prove the accuracy of the model are compared with the results obtained by
experimental method. The effects of the change in the orientation angles of the
antisymmetric carbon and glass fibers on the in-plane vibration properties of
the FML plates under various boundary conditions were numerically investigated.
Numerical analyzes were carried out parametrically. Finally, the most important
layer configurations that are effective in the vibration characteristics of the
hybrid structure have been obtained.
