Work Group Material Fatigue

 

The Fatigue Strength group investigates the fatigue behaviour and fatigue strength of materials with structural defects, such as cast iron, powder metallurgical steels and tool steels. A further research focus is the component design. The focus is on the vibration-resistant design of multi-axial, non-proportionally loaded components, component design based on concepts of short-crack fracture mechanics and fracture statistical concepts. For the experimental investigation of the fatigue strength of specimens and components, a large test machine park is available. In addition to axial, torsional, bending and rotating bending loads, multi-axial tests can also be performed.
