Abstract EN
This paper aims at developing a mathematic model to characterize the mechanical properties of single-walled carbon nanotubes (SWCNTs).
The carbon-carbon (C–C) bonds between two adjacent atoms are modeled as Euler beams.
According to the relationship of Tersoff-Brenner force theory and potential energy acting on C–C bonds, material constants of beam element are determined at the atomic scale.
Based on the elastic deformation energy and mechanical equilibrium of a unit in graphite sheet, simply form ED equations of calculating Young's modulus of armchair and zigzag graphite sheets are derived.
Following with the geometrical relationship of SWCNTs in cylindrical coordinates and the structure mechanics approach, Young's modulus and Poisson's ratio of armchair and zigzag SWCNTs are also investigated.
The results show that the approach to research mechanical properties of SWCNTs is a concise and valid method.
We consider that it will be useful technique to progress on this type of investigation.
