    "abstract": "The fracture of carbon nanotubes is studied by atomistic simulations. The\nfracture behavior is found to be almost independent of the separation energy\nand to depend primarily on the inflection point in the interatomic potential.\nThe rangle of fracture strians compares well with experimental results, but\npredicted range of fracture stresses is marketly higher than observed. Various\nplausible small-scale defects do not suffice to bring the failure stresses into\nagreement with available experimental results. As in the experiments, the\nfracture of carbon nanotubes is predicted to be brittle. The results show\nmoderate dependence of fracture strength on chirality.",
