It is shown that the necessary parameters for an invariant description of the elastic behaviour of a transversely isotropic medium in terms of the spectral decomposition of its compliance tensor are the four eigenvalues of it and a dimensionless parameter, appropriately defined, the eigenangle ω. A study of the variational bounds imposed by thermodynamic restrictions on the values of the eigenangle ω is presented. It is further proposed that the eigenangle ω can be successfully used as a single parameter characterizing qualitatively both elasticity and toughness of transversely isotropic media. © 1990 Springer-Verlag.
