This paper investigates the mechanical behaviors of functionally graded multilayer nanocomposite beams reinforced with a low content of single-layer graphene oxide powders (GOPs). The material properties of GOP nanocomposites are estimated. The first-order shear deformation theory and Hamilton's principle are employed to deal with the motion equations. Parametric studies are conducted to examine the effects of distribution pattern and weight fraction of GOPs, slenderness ratio and boundary condition on the bending, buckling, and vibration of GOP beams. The results show that GOP is superior to the single-walled carbon nanotubes (SWCNTs) and multi-walled carbon nanotubes (MWCNTs) in reinforcing the mechanical behaviors of polymer nanocomposite.
