W ramach teorii zmiennych wewnętrznych, których podstawy termodynamiczne podaliśmy w cz. l rozprawy, dyskutowane są modele lepkoplastyczności i plastyczności stali. Szczególną uwagę zwraca się na modele plastyczności z izotropowym i kinematycznym wzmocnieniem zarówno w przypadku materiału wstępnie izotropowego, jak i anizotropowego. Sformułowane wnioski dotyczą głównie zakresu stosowalności omawianych modeli do analizy sprzężonych efektów termicznych i mechanicznych.

In the framework of the theory of internal variables described in Part l of this paper the discussion on elastic-plastic and vicoplastic constitutive models of steel is presented. Isotropic and kinematic hardening of steel is considered. Conclusions are drawn with regard to the practical application of the discussed models in the thermo-mechanical analysis of steel welded joints by the computer code ABAQUS.
