Analytical Description of the Steady-State Creep of Metals in the Presence of Direct Current
Year: 2019
Type: article
Abstract: This paper is aimed to develop a model for the analytical description of the effect of direct current (DC) upon the steady-state creep of metals.For the mathematical apparatus, the synthetic theory of irrecoverable deformation is taken.As a result, relationships between creep rate, stress, temperature, and current intensity have been derived.For this purpose, a term, taking into account the passing of DC, is entered into the constitutive equation of the theory.The model results fit well experimental data.The analysis of loading surface in steady-state creep for the ordinary loading and that coupled with DC is provided.
