Multiaxial fatigue behaviour of maraging steel produced by selective laser melting
Materials & Design, 2021 This paper studies the multiaxial fatigue behaviour of maraging steel samples produced by selective laser melting. Hollow cylindrical specimens with transverse circular holes are subjected to different in-phase bending-torsion loading scenarios.

Study on crack propagation of 42CrMo
Metalurgija, 2019 For the fatigue failure of 42CrMo, the tensile test was performed on the CT specimen at different load ratios using a fatigue tensile tester. Data on the fatigue crack growth rate of the material and the crack tip factor were obtained.

A dimensional analysis approach to fatigue in quasi-brittle materials
Fracture and Structural Integrity, 2013 In this study, a generalized Barenblatt and Botvina dimensional analysis approach to fatigue crack growth is proposed in order to highlight and explain the deviations from the classical power-law equations used to characterize the fatigue behaviour of ...
