Query: Tensile Strength of Carbon Nanotubes under Realistic Temperature and
  Strain Rate   Strain rate and temperature dependence of the tensile strength of
single-walled carbon nanotubes has been investigated with molecular dynamics
simulations. The tensile failure or yield strain is found to be strongly
dependent on the temperature and strain rate. A transition state theory based
predictive model is developed for the tensile failure of nanotubes. Based on
the parameters fitted from high-strain rate and temperature dependent molecular
dynamics simulations, the model predicts that a defect free $\mu m$ long
single-wall nanotub at 300K, stretched with a strain rate of $1%/hour$, fails
at about $9 \pm 1%$ tensile strain. This is in good agreement with recent
experimental findings.
