采用体心立方α-铁的两个（010）面中236个自由原子组成的模型，对稳态裂纹扩展进行了数值研究。连续体区域采用有限元法建模，具有175个节点和288个单元。在中等载荷下，该模型显示出离散区域边缘的明显（010）平面断裂。分析所获得的结果表明，这种类型的模型可以提供真实的模拟稳态裂纹扩展。
Steady state crack propagation is investigated numerically using a model consisting of 236 free atoms in two (010) planes of bcc alpha iron. The continuum region is modeled using the finite element method with 175 nodes and 288 elements. The model shows clear (010) plane fracture to the edge of the discrete region at moderate loads. Analysis of the results obtained indicates that models of this type can provide realistic simulation of steady state crack propagation.
