Abstract
![CDATA[This paper investigates the linear free vibration of functionally graded (FG) nanocomposite beams reinforced by single-walled carbon nanotubes (SWCNTs). The 3rd order shear deformable beam theory is employed in this study. It is assumed that the SWCNTs are aligned along the beam axis direction and the distribution of the SWCNTs may vary through the thickness of the beam. The virtual energy functional of the FG-CNT composite beam is obtained using the classical variational method of Hamilton’s principle and then is solved by the Ritz method. Two types of CNT reinforced beams, namely uniformly distributed CNT reinforced (UD-CNT) beams and functionally graded CNT reinforced (FG-CNT) beams, are investigated. Vibration frequency parameters for the FG-CNT beams are presented and the effects of CNT filler volume fraction, distribution, beam slenderness ratio and end support conditions on the free vibration characteristics of the beams are discussed.]]
