Kiryk, R.; Petryk, H. A self-consistent model of rate-dependent plasticity of polycrystals. (English) Zbl 0940.74013 Arch. Mech. 50, No. 2, 247-263 (1998). Summary: The Hill-Hutchinson self-consistent scheme for polycrystals is extended to rate-dependent plasticity with work-hardening. A computational version of the model requires three material parameters for a single crystal, which are approximately identified from the experimental stress-plastic strain curve for a polycrystalline material. Contours of the macroscopic plastic potential are calculated after different plastic prestrains in uniaxial tension.
