An expression for the angle between the symmetric stress deviator and the strain-rate deviator in a tensor nonlinear isotropic continuum is derived. A dependence of this angle on a certain orientation parameter in the three-dimensional principal strain-rate space is analyzed.

Key words: tensor nonlinearity, constitutive relation, material function, isotropic medium, deviator, stress, strain rate.
