Experimental setup and material
The stress-controlled single-stage tests were carried out on a Shimadzu type EHF-U servo-hydraulic test system with a maximum load of 50 kN, a frequency of f = 5 Hz, a sinusoidal load-time function, and a load ratio of R = -1 at room temperature with RT = 25°C.
The specimens were stressed to failure or to reach th
Lifetime calculation according to the SteBLife method
The specimens used in SteBLife are characterized by a stepped geometry with different test section diameters, which leads to different local stress amplitudes along the specimen axis under cyclic loading (Fig. 2, bottom left).
The fatigue tests are carried out at a constant force ampli

Summary
The paper shows how non-destructive measurement methods based on temperature can be used in the context of short-term procedures for service life calculation. The procedure is presented using the example of normalized carbon steel grade C45E and the SteBLife method.
SteBLife opens up the possibility of providing signif

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
