摘　　要：用三维各向异性有限元法，对铜三晶体在拉伸载荷作用下的弹性应力集中特性和各组元晶体主滑移系上的切应力变化进行了计算分析，得到了与实验较为一致的结果，为进一步分析三晶体的循环塑性变形提供了依据．The elastic stress distribution around a triple junction and the resolve shear stress along primary slip system in each component crystal of a copper tricrystal were analyzed by 3-dimensional anisotropic, finite element method. The calculated results were compared with that of observed by experiments.
