Abstract

The study of mechanical properties of graphene is one of the hottest topics in graphene physics. As the number of graphene layers increases, the mechanical property changes. Y. Liu et al., J. Mech. Phys. Solids, 60, 591 (2012) [1] have studied the tensile force and shear strain of bilayer graphene. They observed both the parameters increase as the length increases. In this paper, we study the same parameters for trilayer graphene. In trilayer graphene, we observe that with increasing length of the material, the tensile force increases and shear strain decreases. The change of mechanical behaviour from bilayer to trilayer graphene is a transition which would continue to higher number of layers with potential implications in near future.
