dc.description.abstract | This paper aims at predicting the fatigue crack initiation life in maraging steel manufactured by selective laser melting under in-phase bending-torsion loading. Three relationships between the bending moment and the torsion moment were studied, namely B/T=2, B/T=1, and B/T=2/3. The tested geometries consisted of hollow cylindrical specimens with lateral holes. The crack initiation and the crack paths were detected in-situ using a high-resolution digital camera. The local stress-strain states at the notch region were accounted for using two alternative numerical models developed within linear-elastic frameworks: (1) a parametric structured mesh; and (2) an automatic unstructured mesh. Fatigue crack initiation sites and fatigue crack initiation lives were successfully predicted using both numerical models. | pt |
