New Considerations on Variability of Creep Rupture Data and Life Prediction

Transactions of the Korean Society of Mechanical Engineers A, 2009
This paper deals with the variability analysis of short term creep rupture test data based on the previous creep rupture tests and the possibility of the creep life prediction. From creep tests performed by constant uniaxial stresses at 600, 650 and 700 elevated temperature, in order to investigate the variability of short-term creep rupture data, the ...

Creep rupture life and variation of micro-structure according to aging time and creep test methods

Materials Science and Engineering: A, 2007
Abstract To investigate the effect of defects on the mechanical property of 9Cr–0.5Mo–1.8W–V–Nb (ASME-P92) alloy, creep rupture and small punch creep (miniaturized disc band) tests were performed. The precipitates and micro-cavities generated during the test periods were investigated quantitatively.

Effect of short-term data on predicted creep rupture life – pivoting effect and optimized censoring

Materials at High Temperatures, 2008
Fitting data to classical creep rupture models can result in unrealistically high extrapolated long-term strength. As a consequence, the standard strength values for new steel grades have frequently needed downward correction after obtaining more long-term test data.

Unreliability in the Prediction of Creep Rupture Life and Its Avoidance

Journal of Pressure Vessel Technology
Abstract Methods of modeling and extrapolating creep rupture data are critically examined, contrasting conventional models evaluated by statistical methods with models produced by the parametric, numerical isothermal datum (P-NID) method developed by the writer.

Fatigue life prediction of filled polypropylene based on creep rupture

Polymer Engineering & Science, 1984
AbstractTo predict the fatigue performance of talc‐filled polypropylene in engineering applications, a simple relationship using constant stress data to predict the cycles‐to‐failure (Nf) was developed: where k and n are constants from creep rupture tests, v is the cyclic frequency (≤1 Hz to avoid self‐heating), f(n) is a function that accounts for ...

Influence of Regeneration Treatments on Creep Rupture Lifes of Turbine Blades

1987
Turbine blades in aircraft gas turbine engines are highly stressed components. They are subjected to a complex combination of different loads, resulting from their specific operating conditions as rotating parts in a corrosive high temperature atmosphere.

Apparent Lowering of Creep Rupture Life by Frequent Beam Leveling

1971
Limited test results reported here and elsewhere suggest that frequent beam leveling may reduce observed rupture life under conditions where the specimen ductility is high. The magnitude of this effect is small compared to the influence of other factors.
