Reliable analysis and extrapolation of creep rupture data

The P-NID (Parametric, Numerical Isothermal Datum) method of extrapolating creep rupture data has been applied to the four large datasets recently analysed by the European Creep Collaborative Committee in order to re-evaluate its own recommended procedure. It is demonstrated from an analysis of these and other datasets that the P-NID method provides a very reliable basis for extrapolation.
