FAM²short
Dr.-Ing. Bastian Blinn
The FAM²short (Fatigue behavior of Additively Manufactured Metals and short-time procedures) group analyzes the fatigue properties of additively manufactured metallic materials. We use efficient short-time procedures such as PhyBaLLIT (Physically Based Lifetime Calculation), which are based on the measurements of a material’s cyclic deformation behavior and physical properties. We also use short-time procedures to characterize conventionally produced metals, e. g., steels and lightweight materials. Because measurements can be applied in variable geometries and used for complex loading conditions, we can investigate the fatigue behavior of components with these short-time procedures, which is useful for condition monitoring. We have a special focus on the PhyBaLCHT method, which involves instrumented cyclic indentation tests and enables a local analysis of a material’s cyclic properties.
