论文摘要
在文献中，定义弹性张量的三角形和立方对称类别之间的关系存在歧义。我们通过检查三角形和立方张量的特征系统和对称组来讨论这个问题。此外，我们提出了数值示例，表明特征值的唯一验证可能导致弹性对称性的识别时混淆。
In the literature, there is an ambiguity in defining the relationship between trigonal and cubic symmetry classes of an elasticity tensor. We discuss the issue by examining the eigensystems and symmetry groups of trigonal and cubic tensors. Additionally, we present numerical examples indicating that the sole verification of the eigenvalues can lead to confusion in the identification of the elastic symmetry.
