Bit Pattern

The effect of boundary conditions on computer simulating dislocation patterns of a fatigued copper single crystals was studied by using the method of discrete dislocation dynamics in two-dimensional system.

利用二维离散位错动力学方法,研究了边界条件对计算机模拟疲劳Cu单晶位错花样的影响,结果表明:边界条件在模拟位错花样这类多体问题时是非常重要的;在其它模拟机制均完全相同的情况下,不同边界条件会形成不同的模拟结果,自由空间边界条件是最简单、也是最不现实的边界条件,模拟结果与实验结果相差甚远;而一维最近邻周期性边界条件与二维近邻周期性边界条件的模拟结果基本相同,与Cu单晶早期疲劳位错花样的实验比较吻合。

During cyclic deformation, the dislocation pattern formed at the early stages and its evolution were simulated by using the method of discrete dislocation dynamics and observed with the electron channeling contract (ECC) technique in scanning electron microscopy (SEM) on a single-slip- oriented copper single crystals.
