Abstract Scope |
Additive manufacturing of metals often produces components that contain internal pores. For eventual qualification and certification, the impact of these internal defects on the failure properties and eventual performance of the material must be understood. This presentation will detail a combined experimental-computational approach for identifying the impact of internal defects on the fracture behavior of additively manufactured metals. In particular, the fracture behavior was experimentally investigated under a range of stress states and with a range of internal pore sizes to determine how the stress state dependent ductility was impacted with increasing pore size. Fracture models used to capture and predict this behavior will be presented. |
