Modified elastic-plastic model: implementation algorithm and comparison of computational efficiency with the elastic-viscoplastic model

Peter Trusov, Pavel Gladkikh

The most important element of mathematical models of thermomechanical processing of metals and alloys is the constitutive model. In recent decades, multilevel physically-oriented constitutive models (CMs) have found widespread application.…
