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 regions, two approaches named as non-bonded interactions and perfect bonding model are utilized and compared against each other. Representative volume finite element (RVE) models are built for a range of CNTRPs and employed for the evaluation of effects of diameter and chirality on the Young's modulus and Poisson's ratio of CNTRPs, for which there is a paucity in the literature. The outcomes of this study are in good agreement with those reported available in the literature earlier. The proposed modelling approach presents a valuable tool for determining other material properties of CNTRPs.

Evaluating the effects of size and chirality on the mechanical properties of single-walled carbon nanotubes through equivalent-continuum modelling Zuberi, M. Jibran S.; Esat, Volkan (2016-10-01) 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. F...
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...
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.
Analysis of crack initiation and propagation in solid rocket motor nozzle throats Nigar, Barış; Özerinç, Sezer; Department of Mechanical Engineering (2019) Graphite is a widely used material in high temperature structural applications due to its high melting point and its mechanical strength and integrity at elevated temperatures. However, rocket nozzles made of graphite are subjected to very high temperatures and pressures that cause cracking and eventual failure. This thesis investigates the reasons of failure and explores design alternatives to overcome this problem. The experimental part of the thesis includes compression tests, tensile tests and fracture ...
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 ...
