Two different definitions of symmetries for photoelasticity tensors are compared. Earlier for such symmetries the existence of exactly 12 classes was proved based on an equivalence relation induced on the set of subgroups of SO(3). Here, an another viewpoint is chosen, and photoelasticity tensors themselves are divided into symmetry classes, accord...

... The concept of symmetry group allows to define an equivalence relation on V, which is coarser than the relation "to be in the same orbit" and defined as follows: two vectors 1 and 2 have the same isotropy class (or same symmetry class in mechanics [22,23] [55,10,48]) that there is only a finite number of isotropy classes for any finite dimensional representation of a compact group. ...
