Creep ratcheting simplified methods experience from structural design of elevated temperature components
During the last decade, advancements in inelastic analysis methods for evaluating elevated temperature structural response have been considerable. Still, the desire to use simplified, less-costly, and easier-to-understand analysis methods for design remains very high. Past activities, using both detailed inelastic and simplified methods, have been very productive. It is instructive to view some of the lessons learned, to assess the technology status, and to provide guidance and identify development needs for future applications. Experience in use of simplified methods and some comparison to results from detailed inelastic solutions are surveyed. Guidance on inappropriate use is also provided as well as identification of domains of applicability for proper use of the various retacheting simplified methods.
