Creep life assessment methods

Abstract Over the past ten years significant progress has been made towards reliable methods for creep life assessment. Through development and application, methods are now at a stage at which their technical viability is established and the cost benefits are proven at the plant operation, maintenance, and strategic planning levels. This paper reviews creep life assessment methods with particular reference to those based on component strain measurement. It is concluded that, through validation, standardization, and data/knowledge banking, consolidation of the substantial amount of information now available must be an objective for the next 5–10 years, whilst not curtailing innovative development.
