Study of damage approaches for life assessment in the creep-fatigue range
This paper presents the final results of the study of design rules for life assessment in the creep fatigue range of metallic structures or components for high temperature applications. The work programme is oulined, including the development of a materials databank, which collects creep fatigue data for high temperature applications. Data on the AISI type 316 austenitic stainless steel and, to a lesser extent on the modified 9 chromium ferritic stainless steel, are considered. The main body of the work critically compares several design rules, with particular emphasis on those that are already included or are being proposed for inclusion in codes and standards of design practice and those that seem most suitable for these applications. The comparison is based on experimental results on AISI 316. The data processed were obtained on smooth specimens at uniformly high temperatures, but they were selected to represent real loading situations, owing to the long duration of the creep phases or to the load history complexity.
