Task

Development of a new safety concept for the evaluation of scrap steel

Goal

Extension of the service life of weirs from the 30s and 40s in German rivers and welding assessment

Path

Recording of design details and typical stresses; development of toughness based safety concepts to avoid catastrophic brittle fracture at low temperatures (winter); correlation of fracture mechanics tests with microstructure to minimize test effort and specimen collection
