    Variable total strain amplitude loading of 316L
    (Technische Universität Bergakademie Freiberg, 2025-05-09) Szlosarek, Robert; Henkel, Sebastian; Nitzsche, Pia
    This project investigates the behaviour of steel 316L under variable total strain amplitude loading, with a focus on understanding the material's response to complex loading conditions. Quasistatic tensile testing and fully reversed constant amplitude fatigue tests were conducted to characterize the material's properties. The variable amplitude tests were performed under total strain control, and the resulting stress-strain hysteresis loops were analysed to reveal the occurrence of mean stress after a drop in strain amplitude. Notably, the sign of the mean stress depends on the direction of strain transition between the tensile and compression domains. Furthermore, an ideal plastic material behaviour was observed after strain increase accompanied by mean stress. To facilitate further research and model development, the experimental data are published in combination with a research paper: Variable strain amplitude loading of steel 316L – experimental results and analytical modelling
