摘要

用Peach-Koehler力分析方法研究了嵌套在无限大矩阵中的方形纳米线界面中滑移位错的平衡位置。研究发现，在纳米线与最近邻的临界距离以下，界面中间位错的稳定平衡位置变得不稳定，在纳米线边缘附近出现两个对称的稳定位置，这是超临界分岔的特征。

Misfit dislocation in the corridor between two neighboring square-shaped nanowires

The equilibrium position of a gliding dislocation in the interface of a square-shaped nanowire embedded in an infinite-size matrix has been investigated from a Peach–Koehler force analysis. It is found that below a critical distance of the nanowire from its nearest neighbor, the stable equilibrium position of the dislocation in the middle of the interface becomes unstable and two symmetrical stable positions appear near the nanowire edges, which is characteristic of a supercritical bifurcation.

期刊介绍： Since 1965, the international journal Acta Mechanica has been among the leading journals in the field of theoretical and applied mechanics. In addition to the classical fields such as elasticity, plasticity, vibrations, rigid body dynamics, hydrodynamics, and gasdynamics, it also gives special attention to recently developed areas such as non-Newtonian fluid dynamics, micro/nano mechanics, smart materials and structures, and issues at the interface of mechanics and materials. The journal further publishes papers in such related fields as rheology, thermodynamics, and electromagnetic interactions with fluids and solids. In addition, articles in applied mathematics dealing with significant mechanics problems are also welcome.
