“…The value of the shear modulus evaluated with the present model is close to most of the values of the shear modulus published by other authors. The current shear modulus evaluated is in satisfactory agreement with the experimental results reported by Hall et al [7]. In general, a good accordance was also observed concerning not only the NCM approach [13,14,17,19,26,28,29,31] (as in current study) but also the MD modelling [10,25].…”

The mechanical behaviour of non-chiral and chiral singlewalled carbon nanotubes under torsional loading is studied. For this purpose, three-dimensional finite element modelling is used in order to evaluate the torsional rigidity and shear modulus. It is shown that the evolution of torsional rigidity as a function of nanotube diameter can be described by a unique function for non-chiral and chiral single-walled nanotubes. A comprehensive study to evaluate the Poisson's ratio of singlewalled carbon nanotubes is also carried out. Two robust methodologies, one for evaluating the shear modulus from results of tensile, bending and torsion tests, and the other to assess Poisson's ratio from results of bending and torsion tests, are recommended.

“…Experimental methods for measuring the elastic modulus of CNTs, based on in situ techniques of atomic force microscopy (AFM) and transmission electron microscopy (TEM) have been established [4][5][6][7]. The common point in the experimental studies is the evidence of unequalled mechanical properties of the individual CNTs.…”

“…Next, we derive the shear modulus of the tube and justify neglecting the shear deflection in the virtual test used for calibrating the angular force. The measurement of the shear modulus is compared to results obtained experimentally [29] and demonstrates the ability of the model to predict mesoscale mechanical behavior of CNTs. Last, a simulation of tube-tube interaction is presented and compared to experimental observations.…”

A mesoscale dissipative particle dynamics model of single wall carbon nanotubes is designed and demonstrated. The coarse-grained model is produced by grouping together carbon atoms and by bonding the new lumped particles through pair and triplet forces. The mechanical properties of the simulated tube are determined by the bonding forces which are derived by virtual experiments. Through the introduction of van der Waals interactions, tube-tube interactions were studied. Owing to the reduced number of particles, this model allows the simulation of relatively large systems. The applicability of the presented scheme to model carbon nanotube based mechanical devices is discussed.

“…To address this question we considered CNT plasticity under another fundamental type of deformation-torsion. Due to recent experimental advances, [10][11][12] it is now possible to probe CNTs as torsional springs. The popular atomistic modeling tools are unsuitable for modeling this type of deformation.…”

Dislocation onset and nearly axial glide in carbon nanotubes under torsion

The torsional plastic response of single-walled carbon nanotubes is studied with tight-binding objective molecular dynamics. In contrast with plasticity under elongation and bending, a torsionally deformed carbon nanotube can slip along a nearly axial helical path, which introduces a distinct (+1,−1) change in wrapping indexes. The low energy realization occurs without loss in mass via nucleation of a 5-7-7-5 dislocation dipole, followed by glide of 5-7 kinks. The possibility of nearly axial glide is supported by the obtained dependence of the plasticity onset on chirality and handedness and by the presented calculations showing the energetic advantage of the slip path and of the initial glide steps.
