论文摘要
晶体材料中的塑性变形受位错的运动和相互作用[和17]控制。现在已经存在离散的位错动力学（DDD）模拟，用于研究中尺度上的塑性流，该塑料流处于两个截然不同的尺度之间的临界位置。在小规模上，原子能模拟特别适合研究单个位错的核心结构或迁移率，而连续方法可以模拟组件尺度上的完整和连续的机械行为。 DDD的目的是模拟大型脱位集合对外部负载的反应，并评估错位的集体行为。
Plastic deformation In crystalline materials is controlled by the motion and interactions of dislocations [AND 17]. Discrete Dislocation Dynamics (DDD) simulations have now existed for about 25 years to investigate plastic flow at the mesoscale, which lies at a critical position between two very different scales. At small scale, atomistic simulations are particularly adapted to investigate the core structure or mobility of individual dislocations, while continuous approaches can simulate the complete and continuous mechanical behaviour at the scale of the components. the purpose of DDD is to simulate the evolution of large dislocation ensembles in reaction to an external load and to assess the collective behaviour of dislocations.
