| Abstract : | This integrated research project (IRP) unites Bombardier and world-leading academic experts from North America (US and Canada) and Morocco to identify and predict the effects of texture and microstructure of two 3rdgeneration Al-Li alloys on their formability and fatigue resistance. The effect of texture on spring-back and fatigue anisotropies will gain a special focus in this endeavor as it constitutes a major barrier which stalls cost-effective implementation of lightweight Al-Li alloys in aging aircraft fuselage. The mechanisms of spring-back and fatigue anisotropy will be identified through in situ testing and advanced microscopy characterization, and then cast into validated multi-scale models able to reliably predict material processing and performance life cycle of the two Al-Li alloys. These models will be leveraged to Bombardier to enable 1) optimization of the die design, tool, and product geometry for various realistic forming processes of floor beam and seat tracks, and 2) structural health prognoses under flight-boundary value conditions of aging aircrafts, respectively. |
