Fatigue refers to the gradual deterioration of a material under alternating or cyclic loads, which may be significantly below its static strength. Service life refers to a component’s ability to withstand irregular, difficult-to-predict loads over its intended service life without failure or loss of function.
The service life of components can be extended through the targeted optimisation of material properties, geometry, surface finish and load histories. Statistical methods are used to assess the probability of failure under varying load conditions and to define safe design limits. The analysis of microstructures, local stresses and notch effects enables the design of components that efficiently withstand cyclic loading and function reliably over the long term.
We are conducting research into the development of new methods and technologies to improve the fatigue behaviour and structural durability of materials and systems. We investigate various aspects, such as material composition, surface design, load histories and temperature conditions, in order to gain a deeper understanding of fatigue processes.
