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
Two factors in particular must be considered here. Relevant damage mechanisms can change from the HCF to the VHCF regime. For example, the crack initiation points shift into the volume in the field of defects, such as inclusions and precipitates, especially in the case of high-strength conditions. In the case of ductile materials, damage developm
Evaluation of the frequency influence on the fatigue behaviour of unalloyed steels
Fatigue life prediction methods (LPV) developed at WWHK in recent years have so far been limited to the transition between LCF (Low Cycle Fatigue) and HCF (High Cycle Fatigue) and to the HCF regime. This has recently led to controversial discussions regarding the ut
