Evaluation of the application potential of non-destructive measurement methods for the characterisation of cyclic deformation behaviour in high-frequency fatigue tests
The weight-optimised component design and the resulting estimation of the fatigue life of metallic materials require a comprehensive understanding of the fatigue processes and th
Use of the electrochemical potential to characterize the surface damage behavior of cyclically loaded materials
As part of the research project, a corrosion measuring set-up is to be set up and integrated into a fatigue testing system (rotating bending machine and/or vibration testing system) so that electrochemical investigations can be carried o
Evaluation of fracture surfaces with regard to damage development of cyclically loaded specimens made of C22E and 20MnCrS5
Within the framework of the planned research project, the aim is to identify the specifics of the fracture surfaces and to record the individual areas quantitatively in order to enable conclusions to be drawn about the materia
As part of the planned research project, fatigue specimens of the steels C22R and 20MnCrS5 will be subjected to conastant amplitude loading with different stress and total strain amplitudes. Within the framework of conventional fatigue tests, it is first of all not possible to make reliable statements with regard to macrocrack formation and propa
For the first experiments in distilled water, a miniaturized electrochemical in-situ cell with a standard three-electrode system, which is also used in potentiodynamic polarization measurements, is being developed. The challenge here is that the cell must be sealed at the sample shafts so that cyclic loading of the specimen can occur in the cell
