Nano-indentation of circular graphene flakes are studied by using MolecularDynamics simulation. We show that the theory of continuum elasticity based onnonlinear F"{o}pple-Hencky equations is applicable on a circular suspendedgraphene flake. Our simulation results are plenty compatible to those resultscalculated by the nonlinear elasticity theory. We find the force-displacementcurves in good agreement with the recent experimental measurements and concludethey are temperature independent. In addition, we find the vibration frequencyfor such a system and monitor that it behaves as a sinusoidal manner at smallcircular graphene size.
