Availability of data
Within the scope of research projects, the raw data commonly used in materials testing are generated in the form of predominantly open formats (e.g. ASCII, csv or TIF). During data collection, not only experimental findings and data derived from them are taken into account, but also the methods used. All research data are comp

SteBLife – A new method for the time- and cost-efficient provision of fatigue data for the safe design of cyclically stressed components and parts for plant and machine engineering
Abstract – The service life of materials and components is limited when they are subjected to repeated mechanical stresses, which is wh
Introduction
Weight-optimized component design and the resulting estimation of the service life or service life of metallic materials require a comprehensive understanding of fatigue processes and the systematic investigation of fatigue behavior. For reasons of time and cost alone, many components can usually neither be built as prototypes nor tes
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
