Multiscale modelling of plastic anisotropy of automotive steels

The proposed project contributes to the development of a multiscale modelling platform for advanced metal forming simulations. For that purpose, suitable parametric representations of the (dual phase) microstructures will be searched and corresponding virtual, microstructure-based RVE generators will be built. The scientific core of the project will be the extension of single phase polycrystal plasticity models available at KU Leuven to dual phase materials, and the integration of these models and their counterparts from MPIE Düsseldorf with adaptive yield locus formulations developed at KU Leuven. Furthermore, texture measurements will be done for model validation purposes. The position forms part of a network project funded by the RFCS program of the EU and involving both academic (TU Delft, MPIE Düsseldorf) and industrial (TATA Steel, ThyssenKrupp Steel, inpro) partners. TU Delft and TATA Steel will provide the experimental validation which is not covered by KU Leuven. The resulting multiscale modelling platform will be used in a benchmark study on the forming process of a safety-critical car body component composed of advanced dual phase steel.
