Abstract: (7090 Views)
In this article, nonlinear bending analysis of single-layered circular graphene sheet is studied. The equilibrium equations are derived based on the nonlocal continuum mechanics and principle of virtual work and first order shear deformation plate theory (FSDT). Differential quadrature method is used to discretize the equilibrium equations. In this method a non-uniform mesh point distribution (Chebyshev- Gauss- Lobatto) is used for provide accuracy of solutions and convergence rate. The effect of nonlocal parameter, thickness, number of grid points and lateral loading are investigated on deflection of graphene sheet. The results are compared with valid results reported in the literature.
