ABSTRACT
The paper is concerned with the generalization of the synthetic theory to themodeling of both plastic and creep deformation. Non-classical problems such as creepdelay, the Bauschinger negative effect and reverse creep have been analytically described;the calculated results show satisfactory agreement with experiments. These problemscannot be modeled in terms of classical creep/plasticity theories. The main peculiarity ofthe generalized synthetic theory consists in the fact that the macro-deformation is highlyassociated with processes occurring on the micro-level of material.
