| Abstract Scope |
Addressing the need for modulus data in plutonium can be done with both mechanical testing and resonant ultrasound spectroscopy (RUS). While RUS is a powerful tool to accurately measure bulk and shear moduli, allowing us to calculate Young’s modulus, acquiring RUS data when investigating materials with texture or voids is not as accurate when compared to more isotropic microstructures. Furthermore, limited work has been done to measure Young’s Modulus using traditional mechanical testing. The density of each sample was measured before measuring C11 and C44 using RUS, and then subsequent mechanical testing at a strain rate of 1x10-3/s was performed on each sample. Comparisons of both measured and calculated Young’s modulus will be reported. A strong collection of Young’s modulus data from both mechanical testing and RUS calculations is necessary to understand the relationship between the two techniques. |
