摘要：
A quasicontinuum (QC) method can effectively reduce the computational demand of atomistic simulations by combining continuum and atomistic approaches. In this paper, the QC method is applied to simulations of crack propagation in materials represented by three-dimensional disordered particle systems with elastic-brittle links. The accuracy and efficiency of different QC approaches are evaluated by comparison with the fully resolved particle model.
