Nanoindentation of a circular sheet of bilayer graphene
arXiv:1105.2514 · doi:10.1103/PhysRevB.81.235421
Abstract
Nanoindentation of bilayer graphene is studied using molecular dynamics simulations. We compared our simulation results with those from elasticity theory as based on the nonlinear Föppl-Hencky equations with rigid boundary condition. The force deflection values of bilayer graphene are compered to those of monolayer graphene. Young's modulus of bilayer graphene is estimated to be 0.8 TPa which is close to the value for graphite. Moreover, an almost flat bilayer membrane at low temperature under central load has a 14 smaller Young's modulus as compared to the one at room temperature.
