... is presented. The proposed design-by-analysis creep-fatigue damage calculation approach uses a new elastic follow-up-based Isochronous Stress Strain Curve stress relaxation procedure. A set of sample problems are selected to validate the proposed design-byanalysis rules for creep-fatigue damage assessment...

... to generate CF failure life information at low strain ranges and long hold times. The CF test was designed for Alloy 617 at 950oC with elastic follow-up effect to slow down the stress relaxation process during the hold time. The test specimen was cycled at higher strain ranges to accumulate enough CF damage...

... specimens to determine the stress triaxiality distributions, local and average stress relaxation behavior, and local elastic follow-up. The results from the experimental and numerical studies on the CF of notch specimens are compared with those on standard uniaxial smooth bar specimens. The notch effect...

... Abstract Elastic follow-up (EFU) is a complex and influencing phenomenon in pressure vessels and piping systems. It affects the performance of structural components at elevated temperatures. Quantification of elastic follow-up is challenging since it’s still not clearly defined in the ASME...

... method into a standard testing method. Scoping test results on Alloy 617 and SS 316H using the newly developed SMT methods are summarized and discussed. The concepts of the SMT methodology for creep-fatigue evaluation are explained. Simplified Model Test creep-fatigue elastic follow-up...

... and displacement-controlled creep-fatigue loading on the SMT cycle life is demonstrated at different strain ranges. The effect of primary load on the SMT design method is discussed. Simplified Model Test creep-fatigue internal pressurization elastic follow-up EFFECT OF INTERNAL PRESSURIZATION...

... interact and to seek a method of measuring elastic follow-up during the interaction. A friction stir welded aluminium alloy plate was subjected to a series of incrementally increasing load and unload cycles, whilst simultaneously measuring residual stresses and deformation. In-situ loading of the specimen...

... When conducting an assessment of the integrity of a structure the user is directed to classify the stresses as either primary stress or secondary stress. Residual stresses are usually classified as secondary stresses unless they exhibit significant elastic follow-up. In this paper the authors...
