Thermoviscoplasticity Theory Incorporating the Third Deviatoric Stress Invariant

The applicability of three versions of constitutive equations to the description of the thermoviscoplastic deformation of isotropic materials is discussed. It is shown that the thermoviscoplastic equations incorporating the third deviatoric stress invariant are in good agreement with experiment
