“…Mechanical properties, such as Young's modulus, ultimate strength and strain, the stress-strain curve for CNTs, were calculated. Additional research uses this approach [116][117][118][119][120]. Using the same method, Xiao et al [115] developed a FE beam model incorporating a modified Morse potential.…”

“…Single-walled carbon nanotubes (SWNTs) are amazing onedimensional systems, characterized by semiconducting to conducting electrical conductivity [1,2], excellent thermal conductivities [3], extremely large aspect ratio [3], impressing mechanical features (such as a Young modulus of the order of 1 TPa) [4,5], and high thermal stability (mainly in inert atmosphere such as nitrogen) [6]. The radial breathing mode observed by Raman spectroscopy in single-walled carbon nanotubes (SWNTs) allows for a direct measurement of the diameter of SWNTs and of the effect of macromolecular chains on their diameter [7].…”

Nanocomposites of single-walled carbon nanotubes dispersed within polyvinylchloride have been obtained by using the solution path. High-power sonication was utilized to achieve a good dispersion of carbon nanotubes. Thermogravimetric analysis revealed that during the synthesis, processing, or thermal analysis of these nanocomposites the released chlorine is functionalizing the single-walled carbon nanotubes. The loading of polyvinylchloride by single-walled carbon nanotubes increases the glass transition temperature of the polymeric matrix, demonstrating the interactions between macromolecular chains and filler. Wide Angle X-Ray Scattering data suggested a drop of the crystallite size and of the degree of crystallinity as the concentration of single-walled carbon nanotubes is increased. The in situ chlorination and amorphization of nanotube during the synthesis (sonication step) is confirmed by Raman spectroscopy.

“…In the analysis of single-walled carbon nanotubes (SWCNs), there are in the literature three-dimensional finite element models 4–6 for armchair, zigzag and chiral SWCNs, wherein the bonds between carbon atoms are considered as connecting load-carrying members, while the carbon atoms as joints of the members. To create the finite element (FE) models, nodes are placed at the locations of carbon atoms and the bonds between them are modeled using the three-dimensional elastic beam elements.…”

Carbon nanotubes are used in several engineering applications because of their superior mechanical properties. Scientific works still need to be carried out, especially on their dynamic response. These studies mainly focus on modal analysis, considering zigzag and armchair nanotubes, and sometimes, varying chirality. However, these works do not present any results on the steady-state responses. Therefore, the objective of this paper is to perform different studies, in terms of the stiffness response, modal analysis and steady-state response of single-walled carbon nanotubes by using a 3D finite-element model of the single-walled carbon nanotube, under different types of boundary conditions, to provide more results in this field. The single-walled carbon nanotube is modeled as a space frame structure by using the Morse potential and as a thin shell model based on various shell theories. A static analysis is performed to compare the stress–strain behavior between the Morse potential and the thin shell model. A parametric study on chirality effects and aspect ratio is also conducted to determine which shell theory is more suitable to model the mechanical behavior of single-walled carbon nanotubes. Finally, the analysis of harmonic response is conducted to describe the steady-state response between both the models.
