Elastic Properties of Carbon Nanotubes and Nanoropes [PDF]
, 1997 Elastic properties of carbon nanotubes and nanoropes are investigated using an empirical force-constant model. For single and multi-wall nanotubes the elastic moduli are shown to be insensitive to details of the structure such as the helicity, the tube ...

Point defect in solids: Shear dominance of the far-field energy [PDF]
, 2007 It is shown that the elastic energy far from a point defect in an isotropic solid is mainly shear elastic energy. The calculation, which is based on a standard dipole expansion, shows that no matter how large or small the bulk modulus is compared to the ...
