Contents

In addition to the classical fatigue processes under constant amplitude loadings at constant temperature treated in the lecture “Fatigue of Metallic Materials I”, numerous technical components are subject to more complex cyclic stress states. These are (i) thermomechanical fatigue due to temporally and spatially variable temperatures, e.g., caused by start-stop processes of facilities operated at high temperatures, (ii) ultra-high cycle fatigue with load cycles beyond the typical fatigue limits at 106 to 107 cycles and (iii) fatigue with load amplitudes and frequencies that change over the service life. In-depth knowledge of the material behavior under such complex loads, and of suitable modeling approaches, is essential for the safe design of a large number of safety-relevant components in mechanical and process engineering.

The lecture first gives an overview of the technical background and experimental investigation of these complex variants of fatigue loading. Then the material behavior in case of thermomechanical fatigue, ultra-high cycle fatigue and variable amplitudes is presented and discussed. The focus here is on understanding the interactions of complex fatigue loadings, microstructure, deformation and damage mechanisms and service life. On this basis, models for service life assessment for the considered types of fatigue loading are presented and evaluated, using exemplary test results.

Competencies / intended learning achievements

The students are able
  • on the level of subject matter expertise:
    • to describe thermomechanical fatigue processes, ultra-high cycle fatigue as well as variable amplitude loadings in components
    • to describe appropriate experimental approaches for the characterization of the material behavior under these load types in laboratory tests
    • to assign and analyze the microstructural damage mechanisms occurring under the considered loading conditions depending on the type of material
    • to describe model approaches for the service life prediction under these types of fatigue loading
  • on the level of methodological expertise:
    • to evaluate these modeling approaches with regard to their suitability against the background of the type of loading and the associated damage processes
