Abstract
The aim of the current work was to study on the effectiveness of combination of multiscale finite element modelling and 3D Digital Materials Representation in prediction of deformation behaviour of microalloyed steel when subjected to room temperature cyclic deformation. During room temperature deformation of microalloyed steel, interactions between fine second phase particles and dislocations affect in a significant and various ways both deformation and precipitation strengthening mechanisms. Accurate reflection of the above-mentioned phenomena in numerical simulation requires, first of all, proper material model that is strain path sensitive. In the present work, combined isotropic-kinematic hardening model was joined together with Digital Material Representation and used for simulation of cyclic deformation plastometric tests. It was found that proposed modelling approach allowed for much more accurate prediction of strain inhomogeneities in deformed specimens. This in turn allowed for better understanding the complex strengthening mechanisms as well as microstructure evolution and provided a link with the mechanical behaviour of investigated steels under cyclic deformation.
