The discussion addresses the description of material behaviour due to stress-controlled load histories. It is restricted to 2D-problems, and a principal stress piane will be employed to demonstrate specified load events, assuming that the principal stress components are fixed to the material element. In order to tracę the general rules of the model evolution, due to the current load development, the assumptions postulated in the original formulation are described. As it was originally composed, the plastic module field and its variations, in respect to the actual load event of the considered load path, will be demonstrated. The attention will be paid to the ability to reproduce the Bausch-inger effect, and the plastic strain accumulation occurring under specific nonpropor-tional load conditions.
