Use of non-destructive testing methods in a new one-specimen testing strategy for estimating fatigue data
The aim of the present research project is to exploit the potential of non-destructive testing methods, the digitalisation of measurement technology and signal processing to combine them with a novel one-specimen testing strategy in order to a

Use of µmagnetic test methods for the evaluation of the damage evolution in metallic materials subjected to cyclic loading
In order to achieve the goal of a (residual) fatigue life calculation for metallic materials or structures, it is necessary that comprehensive information is determined and made available. This information descri

In the case of a pressurized pipeline filled with superheated steam or supercooled water, it must be assumed after a certain operating time that the local scatter of the material properties specific to the loads continuously increases.
The effects of such influences are currently covered in general terms by safety factors in
MibaLeb is expected to make a decisive contribution to this. The overall goal of the second project phase is to transfer the results, findings and methods to real and actually loaded materials and components in order to provide reliable information on the integrity and remaining service life of nuclear power plants.The aim of the WWHK subproject
Tissue engineering of cells in complex hydrogels using three-dimensional electrical and magnetic stimulation
The project is located in the field of tissue engineering. Tissue engineering refers to the production of tissue replacements in the laboratory. The aim is the production of intestinal wall analogue tissue from muscle and nerve cel
For this purpose, measurements on fatigue specimens are carried out on the steel 20MnMoNi5-5 in a service relevant heat treatment condition, in which the residual stresses are determined conventionally using an X-ray diffractometer and then the results are used in order to calibrate the µmagnetic measuring system.The surface roughness is measured
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
