The symmetric fourth order tensor, with symmetry in the first two dimensionss and skew-symmetry in the second two. More...

Detailed Description

The symmetric fourth order tensor, with symmetry in the first two dimensionss and skew-symmetry in the second two.

Mandel notation/reduced skew is used, and so the storage space is (6, 3).
