| Abstract Scope |
Additive manufacturing has enabled the fabrication of complex part geometries using less material than traditional methods. However, these parts may be limited in their fatigue performance due to the as-deposited surface roughness imposed by the processing technique. As techniques such as hand finishing may not be viable for complex geometries, novel technologies must be employed to reduce the roughness. In addition, demonstrating the ability to reduce fatigue life uncertainty through data collection and modeling techniques will be crucial to enable the adoption of materials and new components. This is being addressed through novel modeling techniques and carefully controlled experimental validation to advance the technologies in this area. Details and results of this approach will be presented. |
