Bosch as a partner for car manufacturer and supplier in the automotive industry develops and produces metallic components, e.g., in the area of electrified cars as well as for cars with internal combustion engines. Thus, one main objective is to provide reliable components with robustness against, i.e., fatigue to fulfill customer requirements. Moreover, it has to be considered that there will be components delivered with high lot sizes, high quality while keeping costs low. Therefore, a very accurate fatigue design and development of materials are necessary. In order to ensure safe use of the components, the existence of natural material defects such as non-metallic inclusions or defects caused by corrosion attack have to be considered. The present presentation gives an overview of some challenges related to fatigue design of automotive components and possible evaluation methods under consideration of defects by using fracture mechanics approaches.
