具有立方晶系结构的多晶体材料的弹性常数——Y弹性常数

The elastic constants of polycrystalline materials with cubic system structural single crystals

提出了一个新的物理参量"Y弹性常数",并阐述了其物理含义.并将其应用于具有立方晶系结构的多晶体材料,推导了立方晶系结构的多晶体材料的Y弹性常数,通过算例与具有立方晶系结构的多晶体材料的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的机械弹性常数的表达式与Krner的研究结果完全符合.

New physical parameters ＂Y elastic constants＂ and their physical meanings are proposed at the first time. The Y elastic constants are applied to the polycrystalline materials with cubic system structural single crystals, and they are deduced and compared with the ＂X-ray elastic constants＂ of polycrystalline materials with cubic system structural single crystals. The expressions of mechanical elastic constants of polycrystalline materials based on Y elastic constants are in good agreement with that proposed by Kroner.
