Energy-based critical plane fatigue methods applied to additively manufactured 18Ni300 steel. International Journal of Fatigue, 170, 107548–. https://doi.org/10.1016/j.ijfatigue.2023.107548 https://hdl.handle.net/10630/26357 https://doi.org/10.1016/j.ijfatigue.2023.107548 In this work, the uniaxial and biaxial fatigue behaviour of maraging steel (18Ni300) obtained by additive manufacturing was studied. The material was evaluated using several biaxial load paths and different load levels. The predictive capacity of the fatigue life and crack initiation angle of the critical plane methods of Liu (I and II), and Chu, Conle, and Bonnen (CCB) were evaluated. The results obtained showed that normal stresses had a strong effect on the fatigue life. In general, the best estimates of the useful life and initial crack angle prediction were obtained with the CCB method. eng http://creativecommons.org/licenses/by-nc-nd/4.0/ open access Attribution-NonCommercial-NoDerivatives 4.0 Internacional Metales -- Fatiga Fatiga (Fisiología) Energy-based critical plane fatigue methods applied to additively manufactured 18Ni300 steel journal article
