Abstract Scope |
Although the ring-pull test is the simplest methodology for testing the hoop tensile properties of cladding relevant geometries, significant artifacts complicate data interpretation. Using digital image correlation, several ring tensile specimen geometries of unirradiated Zircaloy-4 were tested to evaluate strain localizations and gradients across the gage sections as a function of sample orientation and gauge dimensions. It was found that ring tensile tests configured with the gage on the side of the mandrel produced severe strain gradients across the wall thickness. Furthermore, ring tensile tests with longer gage lengths produced severe strain localizations near the specimen shoulders for all orientations, while the gage center remained undeformed. It was found that a ring tensile test with 1.5 mm gage length with gage on top of the mandrel produced a uniform deformation across the entire gage length up to the UTS and did not produce strain gradients across the tube wall thickness. |
