“…Since the publication of the seminal works by Odegard et al [40,41], much has been done in the development of beam FE models for nanotubes and graphene. Regarding graphene, excellent models have been proposed by Scarpa et al [42], Georgantzinos et al [43], Chandra et al [44], Rouhi and Ansari [45], Theodosiou and Saravanos [46], and Zhang et al [47]. However, FE method has not yet been applied to study the mechanical behavior of graphyne, even if for its simple linear elastic behavior.…”

“…Investigating the influence of Stone-Wales defects on the tensile properties of a graphene sheet, Ren an Cao [21] have reported that this type of defect does not have any influence on the Young's modulus and Poisson's ratio using density functional theory. Elastic mechanical properties of graphene sheets have been computed by Georgantzinos and his co-workers using spring elements and incorporating either linear or nonlinear interatomic potential [22,23].…”

“…Fracture strains of GNR have been investigated in the previous works, measured from 0.165-to-0.382. [71][72][73][74] Georgantzinon et al 73 the fracture strain is 25.7% using the Morse potential and a fracture strain of 26.9% using molecular mechanics theory. The limit for the elastic deformation of the GNR extends up to 20%.…”

“…The limit for the elastic deformation of the GNR extends up to 20%. [71][72][73][74] While the buckling in the deformation processes of CNT is inevitable, there is no phoneme of buckling in graphene. 71 74 Therefore, the GNR based NEMS relay has a great advantage in large sensing range, reproducibility in performance without hysteresis, and stability in mechanical operation.…”
