Research with Neutron and Synchrotron Radiation on Aerospace and Automotive Materials and Components
A 3-minute read
This study focuses mostly on advancements in light-duty vehicles and commercial passenger aircraft. Assessments are still being conducted in the areas of improved and partially new materials for reducing airframe weight and joining by laser-beam welding and produced materials, manufacturing processes, and aerospace components.

High-energy synchrotron X-ray diffraction studies are particularly helpful in this situation for examining the stress fields surrounding a fatigue crack and seeing nonlinear effects, such as those brought on by an overload. Plastic finite element simulations. High-1) resolution synchrotron X -ray microtomography is a useful method for understanding the mechanics of microcracking microcracking ro cracking ro image of the position of the microcracks.
