TLDR
Theoretical calculations suggest that single-walled carbon nanotubes are polygonized when they form bundles of hexagonal close-packed structure and the intertubular gap is smaller than the equilibrium spacing of graphite.Abstract:
Single-walled carbon nanotubes show linear elasticity under hydrostatic pressure up to 1.5 GPa at room temperature. The volume compressibility, measured by in situ synchrotron x-ray diffraction, has been determined to be $0.024\mathrm{GPa}{}^{\ensuremath{-}1}$. Theoretical calculations suggest that single-walled carbon nanotubes are polygonized when they form bundles of hexagonal close-packed structure and the intertubular gap is smaller than the equilibrium spacing of graphite (002) $(d\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}3.35\phantom{\rule{0ex}{0ex}}\AA{})$. It has also been determined that the deformation of the trigonal nanotube lattice under hydrostatic pressure is reversible up to 4 GPa, beyond which the nanotube lattice is destroyed.read more

Dynamics of the radial deformation recovery process of single-wall carbon nanotubes
Yanting Shen,Dominic Zerulla +1 more
TL;DR: In this article, a stable deformed state exists as a result of van-der-Waals-interactions within individual tubes and specifically that these tubes can fully recover from this deformation state on surprisingly long time scales on the order of tens of minutes.
