In this letter the author calculate, by applying fracture mechanics, Young’s modulus reduction for a nanotube, imposed by the presence of nanodefects, with specified size, shape, and number. The results are compared with atomistic and continuum simulations. Vacancy fraction, eccentricity, orientation, and interaction of defects are found to be the key parameters influencing the stiffness degradation.
