Abstract:

The objective of this investigation was to study the mechanisms of failure under conditions of creep-fatigue interaction, and creep-crack-growth. The approach was to identify the mechanisms and then develop models for describing failure in terms of the loading variables and the microstructure. In the following sections, the results from each topic are summarized. Further details of the work are available in publications. Author
