Lifetime estimation of high-temperature components made of ferritic sheet metal

Lightweight and economic hot-end exhaust components can be made from ferritic sheet metals. The design of such components is difficult, because materials are pushed to their limit. To support the design process, experimental investigations and consecutively models for deformation and damage were set up within the joint FVV research project. The project was carried out by the Fraunhofer Institute for Mechanics of Materials IWM and the Center for Construction Materials of the Technical University of Darmstadt. The models are available to be used in conjunction with finite element analysis.
