| Abstract Scope |
Mechanically evaluating tube material is difficult, particularly in the hoop direction. While tensile samples may be extracted to test along the length of the tube, microstructural anisotropy due to processing means those results do not necessarily represent the tube properties in the hoop direction. Compounding the problem is that common techniques for testing tubes, such as burst tests, are difficult to implement and require large quantities of material. Research will be presented on efforts to refine a ringpull mechanical testing technique using analytical strain calculations and digital image correlation. As a result a test fixture was developed that can accommodate a range of tube diameters while being suited for hot-cell testing environments for activated samples. Test results will be from accident tolerant FeCrAl fuel cladding. |
