| Abstract Scope |
Fatigue behavior of severely notched cylindrical specimens made of additively manufactured 17-4 PH stainless steel has been studied in the present paper. The test samples were subjected to multiaxial loading condition and the fatigue strength and failure mechanisms of the specimens under different loading conditions were evaluated. Scanning electron microscopy (SEM) was used to analyze the fracture surfaces of the tested samples. The microstructures of the tested specimens were then evaluated using both optical microscopy and SEM. The experimental results were preliminary analyzed by using the Smith-Watson-Topper (SWT) equation and the critical plane approach to obtain a master curve enabling to predict the fatigue life of other components with different geometries and loading conditions. A promising agreement was obtained from the theoretical analyses of the notched components based on these criteria. |
