Research
I want to understand the mechanical properties of material microstructures "from the bottom up", where the bottom can be the behaviour of atoms or even electrons in the microstructure.
I'm investigating the impact of defects (mainly phase and grain boundaries) in metals and alloys on the mechanical properties of microstructures and try to relate these effects to the fundamental defect properties like structure, stiffness and strength. Ideally, these relationships can be captured by analytic expressions which can serve as constitutive relationships for multiscale mechanical modeling.
Competences
