Creep crack growth models damage

The resulting stress rupture data will be used to examir ie the applicability of a generalized fatigue-life (slow crack growth) model. If necessary, model refinements will be implemented to account for both crack blur tlng and creep damage effects. Insights obtained from the characterization studies will be crucial for this modification process. 

Validated models for creep damage assessment are available and these can produce estimates of time to crack initiation. High-temperature crack growth models can then be used to predict both time to failure and the nature of that event.
