| Abstract Scope |
To address issues related to the qualification and certification of additive manufactured (AM) parts, we introduce the One Part And Life (OPAL) framework that leverages advanced in-situ sensors to generate defect and microstructure twins that inform a microstructure based lifing tool. Here, the microstructure based lifing tool (DARWIN®) provides unique life and risk estimates for each AM component. To address fatigue life variability, we expanded DARWIN’s microstructure-based lifing capabilities that previously utilized average grain size to adjust fatigue crack growth (FCG) rates for wrought Inconel 718. As this approach is not readily applicable to AM microstructures with columnar grain structures, here we showcase results from recent efforts that employ a novel crystal plasticity assessments to relate FCG rates to local AM-relevant microstructural features. This presentation will summarize experimental testing, calibration efforts, validation activities, and its impact on fatigue life assessments. |
