摘要：

A single-beam model is presented for investigating the nonlinear vibrations of single-walled carbon nanotubes (SWNTs) embedded in an elastic medium. The thermal effect is also incorporated into the formulation. The variational iteration method is used to solve the corresponding nonlinear differential equation. The amplitude frequency curves for large-amplitude vibrations are graphically illustrated. The influences of thermal effect, some commonly used boundary conditions, changes in material constant of the surrounding elastic medium and variations of geometrical parameters on the vibration characteristics of nanotubes are studied. The results obtained are compared, where possible, with those from the open literature. This comparison clarifies the accuracy as well as the capability of the present method. (C) 2010 Elsevier B.V.
