Popis: Newly acquired test data for AISI type 316 SS at the ambient temperature under monotonic and jump tension, uniaxial complex strain-controlled cyclic loading, and monotonic torsion are presented. Differences in initial yielding and in deformation-induced anisotropy between uniaxial tension and torsional shear are exhibited. On the other hand, Chaboche unified theory of viscoplasticity is adopted to model the observed tensile response and predict new more complicated ones. Modifying the von Mises criterion used in the theory by means of a Hill-type anisotropic tensor allows the theory to predict more accurately the torsional shear response as well.
