In the first approach the effect of the stress-strain state type is taken into account starting from the deviators proportionality hypothesis when the proportionality coefficient depends on the third invariants of stress and strain deviators. In the second approach the effect of the stress state type is taken into account starting from the experimentally justified hypothesis of the existence of the unified longterm deformation diagram on the "strain intensity - time" coordinates under the constant value of the stress intensity.
