Christer Persson is leader for the Materials Technology Group at the Department for Materials and Production Technology. The research of the group is focused on mechanical properties of metals. Important research areas are thermo-mechanical fatigue and contact fatigue, and the applications can be found in the auto, railway and aero industries. In the research are mechanical testing, materials characterization and numerical modeling combined to give knowledge of deformation and fracture mechanisms. The overall aim is to develop better models for life prediction, and thereby contribute to increased safety and lower environmental impact.
