G. Saccomandi et M. Vianello, A UNIVERSAL RELATION CHARACTERIZING TRANSVERSELY HEMITROPIC HYPERELASTIC MATERIALS, Mathematics and mechanics of solids, 2(2), 1997, pp. 181-188
A relation between strain and stress, which is satisfied by transverse
ly hemitropic hyperelastic materials for all finite deformations, is s
hown to characterize completely this symmetry class.
