Size Dependence of the Nonlinear Elastic Softening of Nanoscale Graphene Monolayers under Plane-Strain Bulge Tests: A Molecular Dynamics Study
Figure 4
(color online) Elastic constant that is computed from the simulation data. (a) Illustration of the size-dependent softening behavior that is common amongst all four graphene monolayers under consideration. (b) Collapse of the size-dependent values of the elastic constant onto a single line on a log scale after multiplication by the size factor .
