Abstract

The elastic modulus and fracturing of single-wall carbon nanotubes are studied through an atomistic-based continuum theory. The interatomic potential used is a modified Morse potential function. The Young's modulus that is predicted agrees well with prior experimental results and the results of atomistic studies. The fracture strain that is predicted also agrees well with the results of prior atomistic studies, but is a little higher than the experimental results. The results show that the fracture strain and fracture strength are moderate, dependent on the chirality of the carbon nanotubes. © 2005 The American Physical Society.
