The effect of interlayer shear on bending property of multi-layer
graphene is investigated using molecular dynamics simulations.
Interlayer shear modulus is three orders lower than in-plane Young's
modulus, thus the bending behavior is dominated by interlayer shear.
Continuum theory and atomistic simulations show that bending rigidity is
proportional to layer number when the layer number exceeds 5. The small
difference of these two proportional constants results from the stacking
pattern, and turbostratic stacking decreases the interlayer shear
modulus. For layer number smaller than 4, intrinsic ripples also play an
important role and further decrease the interlayer shear modulus. (C)
