▎ 摘　　要

The buckling of dislocation in graphene is discussed through the lattice theory of dislocation and elastic theory. The approximate solution of the buckling is obtained based on the inner stress distribution caused by different structure of dislocations and is proved to be suitable by the simulation. The position of the highest buckling is predicted to be at the vertex of the pentagon far away from the heptagon. The buckling is strongly influenced by the internal stress and the distance between the extrusive area and stretching area, as well as the critical stress sigma(c). The SW defect is proved to be unbuckled due to its strong interaction between extrusion and stretching. (C) 2016 Elsevier B.V. All rights reserved.
