The fatigue tests are carried out at a constant force amplitude Fa or stress amplitude σa and the material response (MR) is recorded using various measuring methods. Due to the geometry of the specimen, 5 alternating deformation curves can be recorded simultaneously. The alternating deformation curves form the basis for the σa-MR correlations
Following the SteBLifemsb approach, the results of the 5 tests carried out are analyzed with respect to the number of cycles NB and the sa-NB relationship (Fig. 4). Both NB and the σa-NB relationship show scatter, which can be attributed to material inhomogeneities, among other things.
According to the Gaussian distribution, NB can be determined
