摘要
采用有限单元法计算三晶体在单向拉伸载荷作用下弹性阶段的应力场,分析了三晶体中各晶粒主滑移系上的切应力分布,计算结果表明,当晶界平行于加载轴时,该晶界对其两侧晶粒有很明显的作用,较大程度的改变晶粒滑移系的形式,而且作用程度要超过三晶交点的作用,倾斜晶界则没有明显的作用.
In order to solve the experimental problem of tricrystal,elastic stress distribution of copper tricrystal under monotonical loading was analyzed by finite element method,the shear stress on slip system in each grain was analyzed.The effect indicate when grain boundary parallel loading direction this grain boundary obviously affect grain on both sides.The effection changed the form of the grain of the slip system,besides,this degree of the effect exceed triple junction.
