摘要：

In the present paper, we propose and study a nonlinear constitutive relation for describing the one-dimensional isothermal rheological processes with monotone loading history in viscoelastoplastic materials. This relation presents the strain at any time moment in terms of the history of variations in the stress and its derivative by means of two integral operators and contains two material functions of the same real argument and ten material parameters determined by the results of tests on material creeping, long-term strength, and strain at a constant loading rate.
