Fatigue test data of S355 steel and 7075-T651 aluminum alloy subjected to in-phase multiaxial cyclic loading with superposed static components
Description
The provided data set includes the applied nominal stress amplitudes and mean values of cyclic loading, and the number of cycles to failure defined as a 20% drop in specimen stiffness. The hourglass-shaped specimens were subjected to cyclic uniaxial plane bending, torsion, and their in-phase combination. The data were collected to verify the multiaxial fatigue life prediction models of parametric form (standard models) and the recently developed model based on the Gaussian process (Karolczuk, A.; Słoński, M. Application of the Gaussian process for fatigue life prediction under multiaxial loading. Mech. Syst. Signal Process. 2022, 167, 108599). The full description of experimental tests can be found in Kluger, K.; Karolczuk, A.; Derda, S. Application of life-dependent material parameters to fatigue life prediction under multiaxial and non - zero mean loading. Materials (Basel). 2020, 13.
