应用Taylor类多晶体塑性模型对轴对称变形下多晶铜的变形织构进行了数值模拟，分析了变形过程中多晶铜弹性模量的各向异性演化情况，并得到了弹性模量的取向分布和纵向各向异性的直观图像。

英文摘要：

Abstract： A Taylor-like polycrystal model was applied to investigate the evolution of the anisotropic behavior of a face centered cubic （FCC） polycrystalline copper, longitudinal elastic anisotropy of the axisymmetry deformation textures was analyzed during the deformation. The contours of elastic module in three-dimensional orientation space were given and analyzed. The portraits of the longitudinal anisotropy were also obtained.
