Özet

In this study, microstructure-dependent static bending analysis of carbon nanotube-reinforced composite (CNTRC) strain gradient microbeams is performed. Four different patterns of CNTs are considered as uniform distribution (UD-Beam), X-Beam, Λ-Beam, and O-Beam. The equilibrium equations are achieved by implementing a variational principle based on Lam's strain gradient theory and several beam theories. Navier's solution procedure is utilized to solve the resulting equation for simply supported boundary condition. The influences of small size, slenderness ratio, loading types, volume fraction and the pattern of reinforcement on the deflections are perused in detail.
