Dynamic stability of CNTs-reinforced non-uniform composite beams under axial excitation loading

This paper presents an analytical study on the dynamic stability of carbon nanotubes (CNTs) reinforced functionally graded composite beams when subjected to axial excitation loading. The are using a I-type CNTs reinforcement. section properties non-uniform assessed Halpin–Tsai model. analysis is performed by Bolotin’s method. Analytical expressions determining free vibration frequency, critical buckling load, and frequency derived, in which both shear deformation rotary inertia effects considered. demonstrates that beam can be improved significantly it
