Due to numerous difficulties associated with the experimental investigation of the single-walled carbon nanotubes (SWNTs), computational modelling is considered to be a powerful alternative in order to determine their mechanical properties. In this study, a novel three-dimensional finite element model incorporating a beam element with circular cross section is developed based on equivalent-continuum mechanics approach. The beam elements are used as the replacement of C-C chemical bonds in modelling SWNTs. Finite element models are generated for a range of SWNTs and employed for the evaluation of effects of diameter and chirality on the mechanical properties including Young's modulus, shear modulus, shear strain and Poisson's ratio of SWNTs. The results of this study are in good agreement with those reported in literature.

Investigating the mechanical properties of single walled carbon nanotube reinforced epoxy composite through finite element modelling Zuberi, Muhammad Jibran Shahzad; Esat, Volkan (2015-03-15) Varying experimental results on the mechanical properties of carbon nanotube reinforced polymer composites (CNTRPs) have been reported due to the complexities associated with the characterization of material properties in nano-scale. Insight into the issues associated with CNTRPs may be brought through computational techniques time- and cost-effectively. In this study, finite element models are generated in which single walled carbon nanotube models are embedded into the epoxy resin. For modelling interface...
Modelling and analyis of multı-walled carbon nanotube reinforced polymer composites Fatima, Bushra; Esat, Volkan; Sustainable Environment and Energy Systems (2016-8) In this study, multi-walled carbon nanotubes (MWNTs) and multi walled carbon nanotube reinforced epoxy composites (CNTRPs) are investigated by means of computational modelling. To begin with, individual tubes of MWNTs are modelled with varying chiralities through equivalent continuum modelling in order to examine their essential mechanical properties including Young’s modulus, shear modulus, and Poisson’s ratio. The finite element models developed incorporate beam elements that represent Carbon-Carbon ...
ESTIMATING THE EFFECT OF CHIRALITY AND SIZE ON THE MECHANICAL PROPERTIES OF CARBON NANOTUBES THROUGH FINITE ELEMENT MODELLING Zuberi, Muhammad Jibran Shahzad; Esat, Volkan (2014-06-27) Carbon nanotubes (CNTs) are considered to be one of the contemporary materials exhibiting superior mechanical, thermal and electrical properties. A new generation state-of-the-art composite material, carbon nanotube reinforced polymer (CNTRP), utilizes carbon nanotubes as the reinforcing fibre element. CNTRPs are highly promising composite materials possessing the potential to be used in various areas such as automotive, aerospace, defence, and energy sectors.
Structural Vibration Analysis of Single Walled Carbon Nanotubes with Atom Vacancies Dogan, Ibrahim Onur; Yazıcıoğlu, Yiğit (2014-11-01) Recent investigations in nanotechnology show that carbon nanotubes have significant mechanical, electrical and optical properties. Interactions between those are also promising in both research and industrial fields. Those unique characteristics are mainly due to the atomistic structure of carbon nanotubes. In this paper, the structural effects of vacant atoms on single walled carbon nanotubes are investigated using matrix stiffness method. In order to use this technique, a linkage between structural mechan...
Computational modelling of carbon nanotube reinforced polymer composites Zuberi, Muhammad Jibran Shahzad; Esat, Volkan; Electrical and Electronics Engineering (2014-7) This thesis investigates the effects of chirality and size of single-walled carbon nanotubes (SWNTs) on the mechanical properties of both SWNTs and carbon nanotube reinforced epoxy composites (CNTRPs). First, a novel 3D beam element finite element model is developed based on equivalent-continuum mechanics approach and used for replacing C-C chemical bond for modelling SWNTs. The effects of diameter and chirality on the Young’s moduli, shear moduli, shear strains and Poisson’s ratios of SWNTs are studied. Fo...
