Abstract
Based on a refined nonlocal theory, the nonlinear free vibration of core–shell nanowires is presented in this paper. This refined model can predict the weakening of interfacial bonding which satisfies the vanishing stress boundary condition at surface and stress continuity conditions at the interface. The nonlinear governing equations and boundary conditions are obtained by using Hamilton’s principle. The whole problem is solved by a second-step perturbation technique. In numerical results, the simply supported core–shell nanowire with inplane immovable is considered. The effects of transverse shear deformation, geometric sizes, and small-scale parameter and interfacial shear stiffness are discussed.
