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
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

Digital handling of measurement data in research
The lectures and laboratories in the Department of Materials Science contain various experiments for the determination of technological or comparable material parameters, which are provided by means of destructive and non-destructive testing methods. In addition to the use of measuring and testing
