“…Initially, we have computed the Young's moduli of (5,5) armchair carbon nanotubes. The predicted initial Young's moduli of nanostructures were 797 GPa, 708 GPa and 682 GPa for the pristine and the defective carbon nanotubes with one and two vacancies, respectively, which agrees well with the experimental value and other theoretical descriptions [1]. However, the numerical values were strongly dependent on the form of the assumed interatomic potential and the form of defects.…”

“…The costs of experimental measurements and uncertainty of the obtained results demand a support from the theoretical description. For example, only for Young's modulus, the reported values oscillate from 0.68 GPa to 5 TPa (e.g., [1][2][3]). Besides, theoretical calculations have predicted failure strains and failure stresses of carbon nanotubes much higher than those of the few direct mechanical measurements [4].…”

The existence of defects in nanostructures has a significant influence on their mechanical properties. A nonlinear finite element model of single-walled carbon nanotube without and with atom vacancy defects is presented. The numerical efficient formulation for carbon nanotubes is discussed considering the geometry, together with a finite element discretization, including the atomic potential. The effective mechanical properties are evaluated based on the homogenization theory. The results for pristine and defective single-walled carbon nanotube are presented in the form of stress-strain curves. Vacancy defects noticeably reduce the failure stresses and failure strains.

“…From the theoretical point of view, predictive models of mechanical property for CNT reinforced polymer composites are still a current issue. In the mechanical modeling of CNTs composites many authors considered nanotubes as short "tiny" fibers [23,24]. Most of the classical approaches for short fibers reinforced polymers [25][26][27] have been used to predict strength and elastic modulus of CNTs composites.…”

AbstractThe potentiality of carbon nanotubes as reinforcement material is not only due to their exceptional high modulus, but also to their high aspect ratio. Indeed, the nanotubes contribution to the mechanical reinforcement in a polymer is strongly dependent on their distribution within the hosting matrix. In fact, the clustering of carbon nanotubes does limit the theoretical enhancement of the composite mechanical properties by a reduction of their effective aspect ratio.In this work, the reinforcement efficiency of carbon nanotubes having different aspect ratios has been experimentally investigated at low filler contents in an epoxy system.From a theoretical point of view, the classical theory (Cox, 1952) concerning the mechanical efficiency of a matrix embedding finite length fibers has been modified by introducing the tube-to-tube Random Contact Model (Philipse, 1996) which explicitly accounts for the progressive reduction of the tubes effective aspect ratio as the filler content increases. The validity of the proposed model was assessed by a comparison

“…The mechanical properties of CNTs have been celebrated for many years and have been the subject of hundreds of experimental and theoretical investigations, as reviewed most recently by Wang et al, 26 and Shokrieh et al 27 As is often cited, the Young's modulus and tensile strength of CNTs are five and 120 times greater, respectively, than those of 304 stainless steel. Although these simple numbers indicate that CNTs are in general mechanically robust, the mechanical properties of CNTs depend on their diameter, number of walls, and aspect ratio.…”
