Аннотация:Under minimal primary restrictions on two material functions of the physically nonlinear Maxwell-type constitutive relation for non-aging rheonomic materials, the general equation of theoretic stress-strain curves family produced by the model under loading and unloading at constant stress rates is derived and analyzed in uni-axial case. The main qualitative properties of stress-strain curves and unloading responses are compared to typical properties of test loading-unloading curves for viscoelastoplastic materials in order to elucidate capabilities of the model, to obtain necessary phenomenological restrictions which should be imposed on the material functions and to find convenient indicators of applicability (or non-applicability) that can (and should) be checked examining test data of a material.
