Abstract

In this article, we present our take on modeling the Bauschinger effect. The main goal is to correlate the microstructure-based modeling developed for uniaxial tension/compression deformation and the tensorial modeling approach of the continuum mechanics. After a brief historial review, we present a microstructure-related model that was proven to provide an adequate description of the Bauschinger effect in terms of kinematic and isotropic strain hardening. Its generalization to the case of multiaxial loading is then formulated in terms of a continuum mechanics model. The full tensorial model developed is now being offered to the solid mechanics and physical metallurgy communities as an advanced modeling tool.
