This postdoc is based at DTU Construct in close collaboration with DTU Physics and sits within an international, highly multidisciplinary team of around eight PhD students and postdocs. The project aims to understand and predict the mechanical behaviour of metals during plastic deformation by combining dislocation dynamics , crystal plasticity simulations , and synchrotron experiments that provide direct images of microstructural evolution. The main research focus is to develop and apply crystal plasticity models to predict how grain orientations, stress states, and mechanical fields evolve as metals deform. You will compare model predictions with first-of-their-kind 3D maps of voids, particles, grain orientations, and stress states obtained from synchrotron measurements, then identify where predictions fail and improve the modelling approach accordingly. The role also includes exploring the formation of dislocation boundary patterns at scales below the usual reach of crystal plasticity by introducing stochastic elements into simulations. In addition to modelling, you will have the opportunity to participate in synchrotron experiments and learn how the experimental data used for validation are generated. The environment is strongly research-oriented, with colleagues working across mechanics, materials science, and physics at DTU.
