摘要: This article presents a dynamic stability analysis of functionally graded nanocomposite beams reinforced by single-walled carbon nanotubes (SWCNTs) based on Timoshenko beam theory. The material properties nanotube-reinforced composites (FG-CNTRCs) are assumed to vary in the thickness direction and estimated through rule mixture. differential quadrature method is employed convert governing equations into linear system Mathieu-Hill from which boundary points unstable regions determined Bolotin's method. Free vibration elastic buckling also discussed as subset problems. A parametric study conducted investigate influences nanotube volume fraction, slenderness ratio, end supports characteristics FG-CNTRC beams. Numerical results for composite uniformly distributed provided comparison.
