Name

CubicRank2Tensor — A rank 2 tensor with cubic symmetry

Synopsis

CubicRank2Tensor(xx)

Description

A CubicRank2Tensor is a symmetric second rank tensor with cubic rotational symmetry. The argument xx is a real number. The structure is shown in Figure 6.122.

[Note] Note

The CubicRank2Tensor is identical to the IsotropicRank2Tensor. Since people are accustomed to specifying isotropic properties in terms of scalars, instead of tensors, OOF2 doesn't actually provide an IsotropicRank2Tensor class. The CubicRank2Tensor is provided simply so that the user interface can present the same symmetries for rank 2 properties as for rank 4 properties.
