... by that of creep rupture data ( Fig. 9b ). This suggests that hot-strength tests could be used as indicators of the temperature sensitivity of creep rupture data, in which case the number of rupture tests required can be dramatically reduced. This second example demonstrates how a well-designed network is able...
