Postdoc Position: Microstructure estimation with electromagnetic sensing
The Chair of Nonlinear Solid Mechanics, Faculty of Engineering Technology, University of Twente, has an opening for a postdoctoral position on the development of a computational homogenization framework for magnetomechanics of finitely deforming polycrystalline materials.
The Challenge
In steel production lines, non-destructive and online electromagnetic sensor measurements are used to infer a material's magnetic properties from sensor signals and relate them to its mechanical properties. To achieve this, it is necessary to systematically understand how magneto-mechanical coupling in the material's evolving microstructure contributes to its polycrystalline magnetic response.
This project aims to build upon ongoing research at UT by developing physics-based models for electromagnetic measurements of steel sheets across a range of grades in a steel production line. The key tasks involve modeling the polycrystalline microstructure of the steel, enriched with the inclusion of magnetic domains using the phase-field method. By coupling magnetic fields with crystal plasticity, we aim to upscale the influence of dislocation density, phase distribution, and residual stresses on the material's transient and nonlinear magnetic response with hysteresis. This approach will enable us to optimize sensor systems based on sensor geometry and location, allowing an accurate prediction of mechanical properties and potentially leading to improved steel production processes.
In this project, you will report your research during bi-weekly meetings of our research group and frequent meetings with the industrial partner. You are encouraged to present your results at international scientific conferences and publish them in academic journals. Furthermore, as a researcher, you will be encouraged to tutor MSc students who do their final assignment on parts of the current research project.
