Abstract

Multi-axial creep is one of the major reasons for the failures of high temperature components,and it is an important factor to be considered in the engineering design.In this paper,the multi-axial creep design approach based on cavity growth mechanisms is generalized.The basic theory for cavity growth is in-multi-axial creep design of elevated temperature components are pointed out and advices for its further re-search are presented.troduced.Five typical multi-axial creep design models based on cavity growth theory are discussed.Applica-tions of these models in R5,RCC-MR,ASME III and VGB-R 509L are analyzed.Difficulties faced in the
- Creep design,
- Multi-axial stress states,
- Void growth theory,
- Applications
