Addendum to: Reliable analysis and extrapolation of creep rupture data

Abstract

This addendum to Reliable analysis and extrapolation of creep rupture data, Int J Press Vessels Pip 2017, covers matters that were insufficiently addressed in the original article. Uncertainties that obscure evaluation of the P-NID procedure by analysis of multi-batch data are addressed by blind testing the procedure for individual batches of an 18%Cr steel, Type 316 SS. Uncertainties that arise in the extrapolation of near-linear rupture curves are addressed by the inclusion of temperature dependence in parametric stress equations. The use of Tensile Strength data as equivalent short-term rupture data is demonstrated and discussed.
