| Abstract Scope |
Additive manufacturing (AM) has seen large interest in recent years for its ability to print complex parts that would be prohibitively expensive or unrealizable using conventional methods. Mechanical properties of AM alloys vary from those of conventional materials largely due to the complex processing conditions inherit to the additive process. Additionally, these complex parts generally have discontinuities (thin walls, sharp edges, holes, etc.) where the thermal history and, hence, properties differ from the bulk. Rather than relying on part-average properties and microstructure; micro-scale, site-specific characterization is required to generate robust predictive models for additive parts. This research focuses on using a micro-mechanical testing apparatus equipped with both monotonic and fatigue actuators coupled with real-time 2D DIC to explore the differences between areas near these discontinuities with those of the bulk of the part to gain a better understanding of how these discontinuities effect the performance of these parts. |
