...), Goldhoff–Sherby (GS) models. It remains a challenge to determine which model is “best”, capable of accurate interpolation and physically realistic extrapolation of creep rupture data for a given material. In this study, metamodeling is applied to create a unified TTP metamodel that combines and regresses...

... with distinct stress R-ratios. Since data from three test series is available, extrapolations are performed to test the adequacy of the model to make extrapolations for stress R-ratios other than those used in the model parameters assessment. Finally, the probabilistic model is used to model the fatigue...

... gaskets based on measurements of gas flow at different pressures. In fact, an extrapolation of the porosity parameter approach ( Grine, L., and Bouzid, A., 2009, “Correlation of Gaseous Mass Leak Rates Through Micro and Nano-Porous Gaskets,” ASME Paper No. PVP2009-77205 ) used to correlate leak rates...

... Sec. VIII Div 2, weld classification approach in PD 5500, and the surface extrapolation-based hot spot stress approach in recently approved European EN 13445 Standards. In support of the on-going ASME Div 2 Code rewrite efforts, a master S - N curve approach has been proposed by Dong et al...

... the accuracy of the evaluated SIFs an existing improved version of the displacement extrapolation method is used. The results clearly indicate that unevenness, as reflected in K IP distributions, depends on both the number of cracks in the array as well as on the cracks’ depths and ellipticities...

... specimens. Larson-Miller parameter extrapolations of stress rupture data indicate a remaining life of about 46 yr for temperbead repairs and 28 yr for PWHT repairs under design conditions of 1000 ° F 538 ° C and 6.6 ksi 46 MPa . Other isostress extrapolation procedures yield lower lives, but the temperbead...
