Christer Persson is the Head of Division for Engineering Materials at the Department of Industrial and Materials Science. The research of his own research 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.
