TLDR
It is reported that kink motion is a universal plastic deformation mode in all carbon nanotubes when being tensile loaded at high temperatures.Abstract:
We report that kink motion is a universal plastic deformation mode in all carbon nanotubes when being tensile loaded at high temperatures. The kink motion, observed inside a high-resolution transmission electron microscope, is reminiscent of dislocation motion in crystalline materials: namely, it dissociates and multiplies. The kinks are nucleated from vacancy creation and aggregation, and propagate in either a longitudinal or a spiral path along the nanotube walls. The kink motion is related to dislocation glide and climb influenced by external stress and high temperatures in carbon nanotubes.read more

Ultra-strength materials
TL;DR: In this paper, an overview of the principal deformation mechanisms of ultra-strength materials is presented, and the fundamental defect processes that initiate and sustain plastic flow and fracture are described, as well as the mechanics and physics of both displacive and diffusive mechanisms.

The Mechanics and Physics of Defect Nucleation
TL;DR: Li et al. as discussed by the authors proposed a first-principle model of nanoindentation and ideal strength to reveal the genesis of materials deformation and fracture, which is based on the Outstanding Young Investigator Award presentation given by Ju Li on April 19, 2006.

How evaporating carbon nanotubes retain their perfection
TL;DR: A mechanism of high-temperature sublimation of carbon nanotubes that does not destroy their ordered makeup even upon significant loss of mass is presented, which explains a broad class of unsettled phenomena when at high temperature or under radiation the nanot tubes do not become amorphous but rather shrink in size nearly flawlessly.

Tensile tests on individual single-walled carbon nanotubes: linking nanotube strength with its defects.
TL;DR: It is noted that till now, only a few sets of CNT fracture measurements have been reported for any tube structure, either individual MWNTs or ropes of SWNTs, and experimental data suffers from various uncertainties arising from e.g. interlayer (or intra-tube) load transfer, layer and/or tube sliding, and the estimation of an effective cross-sectional area.

On the Theory of Dislocations
TL;DR: In this article, it was shown that dislocations of a more general type than encountered in classical theory can be obtained for states of plane and anti-plane strain in a hollow right circular cylinder when the surface of discontinuity is a single stationary plane barrier.
