Nonlinear Thermo-Nonlocal Vibration of Annular Graphene Sheet on Visco Pasternak Foundation by DQ Approach

چکیده مقاله

In this study, small scale effect [1] on the nonlinear vibration of annular graphene sheet under thermal field is investigated. The graphene sheet is resting on visco-Pasternak foundation [2, 3], where this foundation is consider the spring, shear and damping effects. To drive higher order nonlinear governing equation, the Hamilton's principle [4] is applied. The Differential Quadrature (DQ) approach [5] is employed to solving the nonlinear equation. The results show that small scale parameter, aspect ratio, temperature change and visco- Pasternak foundation have highlights influence on the nonlinear vibration of annular graphene sheet. Present work can be used to design of nano disks in nano robots.
