摘要

晶体中的缺陷影响并控制着许多相关的材料特性。要了解晶体缺陷的结构和演变，必须采用多尺度建模。大多数多尺度建模方案在本质上是分层的，通常将在每个连续长度/时间尺度上进行的建模结果传递到下一个（多个）更高的尺度，目的是为模型参数提供信息或指导简化阶模型的形式。在此，我们简要回顾了晶体缺陷基本原理的一些相关分层多尺度建模进展。

Multiscale modeling of crystal defects in structural materials

Defects in crystals influence and control many relevant material properties. It is essential to employ multiscale modeling to understand structure and evolution of crystal defects. Most multiscale modeling schemes are hierarchical in nature, typically passing results from modeling conducted at each successive length/time scale to the next higher scale(s), with the intent to inform model parameters or instruct the form of reduced-order models. Here, we briefly review some pertinent hierarchical multiscale modeling advances for fundamentals of crystal defects.

期刊介绍： MRS Bulletin is one of the most widely recognized and highly respected publications in advanced materials research. Each month, the Bulletin provides a comprehensive overview of a specific materials theme, along with industry and policy developments, and MRS and materials-community news and events. Written by leading experts, the overview articles are useful references for specialists, but are also presented at a level understandable to a broad scientific audience.
