Angle between deviators of stress and strain rates in a tensor-nonlinear isotropic medium / D. V. Georgievskii. //Vestnik Moskovskogo Universiteta. Seriya 1. Matematika. Mekhanika. 2013. № 6. P. 63-66 [Moscow Univ. Math. Bulletin. Vol. 68, N 6, 2013.].
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.
