| Abstract Scope |
Gaugeless ringpull testing is a convenient test to evaluate the cladding in the hoop direction, due to the fact the samples are easy to machine remotely for activated materials, however, the results are complicated to interpret. The impact of differences in fixture design are important and not well understood, making comparisons between tests performed by different groups difficult. To better understand the impact of mandrel sizes, a range of mandrel diameters were used to test accident tolerant C26M FeCrAl alloy. Global stress and strain measurements were investigated as well as local digital image correlation strain measurements. The measured 0.2% offset stress as well as the ultimate stress, showed no statistically significant differences with respect to mandrel diameter. The elongation measurement, on the other hand, was shown to be highly dependent on mandrel diameter. This talk will go through considerations for mandrel size choice based on tube geometry. |
