简述了运用晶体相场模型研究塑性变形时加载应变的两种主要数值计算方法：变体积方法和等体积方法。论述了两种形变方法的基本原理、求解方法和特点。概述了国内外基于晶体相场模型的塑性变形研究现状，包括二维情形下双晶结构和纳米多晶结构的塑性变形机制研究及“反霍尔佩奇”关系的研究。最后指明了晶体相场模型在塑性变形数值模拟中进一步的研究方向。
英文摘要：
The major numerical schemes of applying strain during phase field crystal plastic deformation simula- tion are introduced briefly, including varvolumetric method and isovolumetric method. The basic principles, solution methods and characterization of these two kinds of numerical schemes are reviewed. The research progress of plastic deformation simulation based on phase field crystal model are summarized at home and aboard, including the plastic deformation mechanism of bicrystalline and nanopolycrystalline materials in two-dimensions and the simulation of the ＂reverse Hall-Petch＂ effect. Finally the future research directions of the phase field crystal model in simulating plastic deformation are pointed out as well.
