    Experimental analysis of residual stress evolution under cyclic mechanical loading in 42CrMo4+QT (1.7225) including parametrization data
    (Technische Universität Dresden, 2024-02-29) Schneider, Tom; Gibmeier, Jens; Kästner, Markus
    This data set contains various results from (cyclic) tests with 42CrMo4+QT/SAE4140. The first part contains the results of cyclic 4-point bending tests on cuboid specimens. They were used to measure the residual stress. Each specimen was loaded with a certain number of load cycles, after which the test was stopped and the residual stress was measured. From this, the development of the residual stresses under the cyclic load can be determined. The second part of the data set contains data from characterization tests. Various uniaxial tests were carried out on a material sample in order to obtain information for the parameterization of numerical models for predicting the development of residual stresses from the first part of this contribution.

    Experimental characterization of fatigue behavior of 42CrMo4+QT material specimens and cross-rolled components
    (Technische Universität Dresden, 2023-08-29) Schneider, Tom; Ellmer, Franz; Guilleaume, Christina; Hantschke, Peter; Brosius, Alexander; Kästner, Markus
    This dataset provides a cyclic material characterization from cyclic tests of material specimen made of 42CrMo4+QT. In addition, fatigue life data are included for cross-rolled components produced with different process variants at different load levels and loadings.

    Mean Stress Sensitivity of Cold-Worked High-Purity Copper: A comprehensive dataset
    (Technische Universität Dresden, 2026-08-25) Schneider, Tom; Schöne, Sebastian; Bohot, André; Lauf, Matthias; Werdin, Sven; Hantschke, Peter; Zimmermann, Martina; Kästner, Markus
    The influence of work hardening on the fatigue behaviour of high-purity copper was investigated using commercially available sheet material (3 mm thickness, as-delivered, no additional rolling or heat treatment) in three strength classes (indicated by their R-number, a measure of minimum tensile strength): R240 (two independently supplied batches, R240-1 and R240-2), R290, and R360. These material states are representative of copper conductors used in electrical applications such as traction motors, generators, and battery systems. For each material state, the dataset comprises: 1. Microstructural characterization by electron backscatter diffraction (EBSD). 2. Quasi-static (monotonic) tensile tests in strain control, using the same specimen geometry as the fatigue specimens (10 mm gauge length; not a standard tensile geometry, so results beyond necking are not comparable to standardized tensile tests). 3. Load-controlled fatigue (Wöhler/S-N) tests on smooth, unnotched specimens at several load ratios, used to quantify the combined effect of mean stress and work-hardening state on fatigue strength. Run-out was defined at 5 10^7 load cycles.
