Abstract

In the present work, the profound information on the mechanical properties of carbon nano-tubes (CNTs) were presented as an application of nano-technology in nano-materials are being most powerful in the current world. This would focuses/emphasis for designing and optimizing the CNTs based materials. Computational modeling technique was applied and developed to examine the mechanical characteristics for single-walled carbon nano-tube (SWCNT) of armchair chirality type. The atomistic based finite element method (FEM) was used to investigate the influence of various geometrical properties (diameter, wall thickness, and height-to-diameter ratio) of SWCNT armchair of chirality type on Poisson’s ratio and Young’s modulus values. Atomistic based finite element modeling was successfully developed and explored the mechanical behaviour of SWCNT exactly. The results were shown that the investigated geometrical parameters had much influenced on the mechanical properties of SWCNTs.

Highlights

Nanotubes are like a powder or dark ash
The mechanical properties of single-walled carbon nano-tube were predicted by utilizing the concept of the finite element model based simulation procedure using tensile test results of SWCNT
Single-walled nano-tube with different geometrical parameters and chirality for armchair type were modeled with bonds between the atoms which considered as a beam element

Summary

Introduction

Nanotubes are like a powder or dark ash. In general, the carbon nano-tube (CNT) is a truly wrapped up graphene sheets that set up empty strings owning dikes with single atom width [1]. The nanotubes are being classified based on several parameters such as construction with one wall, construction with several walls as much as possible and the arrangement of carbon nano-tubes (CNTs) [1,2,3,4,5]. Both single wall nano-tube (SWNT) and multiple wall nanotubes (MWNTs) are being used as commercial products in numerous applications in day-to-day life [5] as the nanotubes products are having much flexibility [4]. The binding of two heads together could form a fullerene [11]
