摘要：
We numerically investigate the scaling of mechanical properties of carbon nanotube bundles, with the objective of evaluating the potential characteristics of large-scale structures. The simulations are carried out using a fibre bundle model adapted at various size scales according to a self-similar scheme. Scaling of both strength and Young's modulus is analysed, comparing results for defective and non-defective bundles, i.e. in the absence or in the presence of voids. Various types of defects are considered, with different size, shape, density and distribution. Analytical laws are also proposed and compared to numerical results.
