摘要
Silicon carbide nanotubes possess outstanding properties which enable them to have many applications. The buckling behaviour of silicon carbide nanotubes have been studied here. To do this, a 3D finite element method, known as space frame model has been proposed. Molecular mechanics are linked to density functional theory to derive the properties of this finite element method. It has been shown that the critical buckling force will diminish with increasing aspect ratio. Also, it is represented that increasing the aspect ratio will result in reducing the effect of boundary conditions. (C) 2012 Sharif University of Technology. Production and hosting by Elsevier B.V.
