In this method, the atomistic method was used to consider the local region around the defect nucleation and fracture position, while the atoms far away from the defect were characterized by a quasi-continuum theory based on the modified Cauchy-Born rule. 在这种方法中,将碳纳米管分成两个区域,在缺陷形核和断裂位置的附近区域采用原子势方法,而在外部区域采用基于修正的Cauchy-Born法则的准连续介质力学方法进行模拟。
