Elastic constants of zirconium alloys

Stress field estimation around a semi-constrained inclusion and its validation by interpreting hydride platelet orientation around a blister in a Zr–2.5Nb alloy

“…(8), was imposed to maintain the contour of notch. Young's modulus for both matrix and d-hydride was taken as 89 GPa [23] and Poisson's ratio of matrix was taken as 0.39 [17]. The geometrical dimensions used in the FEA are listed in Table 1.…”

Predictive Bias and Sensitivity in NRC Fuel Performance Codes

“…Based on these comparisons, it can be seen that the cladding yield stress model in FRAPCON and FRAPTRAN provides a best-estimate prediction of yield stress over a wide range of temperature, fluence, cold work, and strain rate. This model is based on data taken using the dynamic method from several different sources on unirradiated cladding (Bunnell, 1977, Armstrong and Brown, 1964, Padel and Groff, 1976, Busby, 1966, Spasic, 1968, Mehan, 1958, and Northwood, 1975. No Young's modulus data was available for irradiated cladding, so data from the Saxton Core II Fuel Performance Evaluation (Smalley, 1971) was used to estimate the effects of fast neutron fluence.…”

Flow behaviour of autoclaved, 20% cold worked, Zr–2.5Nb alloy pressure tube material in the temperature range of room temperature to 800 °C

“…Following an iterative method, a numerical value of the load train stiffness for each test was evaluated such that the correction in the foot corrected load-deflection curve based on this numerical value would result in engineering stress-strain curve whose initial slope would match the Young's modulus values for Zr-2.5Nb alloy reported by Northwood et al [34].…”
