Bending of functionally graded carbon nanotubes/fiber-reinforced composite laminated shells

Ahmed Amine Daikh , Mohamed A. Eltaher

Abstract

In order to analyze the bending behavior of functionally graded carbon nanotubes (CNT)/fiber-reinforced composite laminated shells, an analytical solution based on the Galerkin technique is proposed. The mathematical formulations are generated based on higher-order shear deformation theory. Various geometrical schemes of shells are analyzed. Three distribution patterns of fibers are examined, FG-X, FG-O and FG-V, in addition to the uniform distribution (UD). The CNTs volume fraction is constant and evenly distributed throughout all shell layers. The virtual work principle is employed to derive the equilibrium equations. The influence of CNTs and fibers proportion, fibers distribution patterns, geometrical parameters and various boundary conditions on the deflection of CNTs/F-RC shells is investigated in detail.
