Evaluation of the application potential of non-destructive measurement methods for the characterisation of cyclic deformation behaviour in high-frequency fatigue tests
The weight-optimised component design and the resulting estimation of the fatigue life of metallic materials require a comprehensive understanding of the fatigue processes and the s
The S-N curve generated using accelerated lifetime prediction methods are based on only a few real data points due to the significantly reduced experimental effort. However, the database can be significantly expanded by generating virtual data points, which makes it possible to integrate statistical methods (Point 1).
In order to describe the s
Initial results on the integration of statistical methods into accelerated lifetime prediction using the example of the material C45E were presented at the conference “Steel Innovation” in April 2025. The procedure for generating an S-N curve with density function, to describe the scatter band, is shown and described below.
