摘要: 利用最近提出的新的物理参量--Y弹性常数,将其应用于具有六方晶系结构的多晶体材料.推导了六方晶系结构的多晶体材料之Y弹性常数,通过算例与具有六方晶系结构的多晶体材料之X射线弹性常数进行了比较.运用这个Y弹性常数进一步推导出的多晶体材料整体之机械弹性常数的表达式与Kneer的研究结果中的表达式虽然形式不同,但针对具体材料所计算的结果却完全符合.Abstract: In this paper, the physical parameters Y elastic constants mewly proposed in our previous paper are applied to polycrystalline materials with hexagonal structure to deduce Y elastic constants thereof and to compare with the x-ray elastic constants of polycrystalline materials of hexagonal structure through calculation of examples. Though the expressions of mechanical elastic constants of polycrystalline materials deduced from the application of Y elastic constants are different from the conclusions of Kneer, the calculated results for concrete materials are in full compliance.
