Evaluation of the frequency influence on the fatigue behaviour of unalloyed steels - Evaluation of the frequency influence on the fatigue behaviour of unalloyed steels

Date: 31.01.2023

Evaluation of the frequency influence on the fatigue behaviour of unalloyed steels The fatigue life evaluation methods (LPV) developed at WWHK in recent years have so far been limited purely to the transition between LCF (Low Cycle Fatigue) and HCF (High Cycle Fatigue) and to the HCF field. This has recently led to controversial discussions regar

Evaluation of the frequency influence on the fatigue behaviour of unalloyed steels

Date: 14.09.2023

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 fracture surfaces with regard to damage development of cyclically loaded specimens made of C22E and 20MnCrS5 - Use of the electrochemical potential to characterize the surface damage behavior of cyclically loaded materials

Date: 14.09.2023

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

Evaluation of fracture surfaces with regard to damage development of cyclically loaded specimens made of C22E and 20MnCrS5

Date: 15.07.2021

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
