Predictive Sequential Life Testing
Biometrika, 1978Sequential tests that are based on some unobservable parameter have been well investigated using both classical and Bayesian approaches; see, for example, Wald (1947) and Barnett (1972). In this paper we use the Bayesian predictive density function to constuct a sequential test that is based on some statistic of a future sample, and investigate the ...

Life Prediction of Notched Components
Journal of Engineering Materials and Technology, 1995In this study, keyhole and smooth specimens, made from a low alloy pressure vessel steel (ASTM A-533 grade B), were subjected to monoaxial fatigue tests. The results show the influence of the stress concentration factor, Kt, on the number of cycles to failure, Nf.

Life Cycle Assessment and Service Life Prediction
Journal of Industrial Ecology, 2014SummaryModels of buildings in life cycle assessment (LCA) often use simple descriptions of operational energy, maintenance, and material replacement. The scope of many building LCAs is often limited and uses assumptions such as building lifetimes of 30 to 50 years.

ABSTRACT The paper addresses a recently developed mathematical model for coiled tubing fatigue life prediction. It is shown that the coiled tubing stress-strain condition is unique and is primarily characterized by plane elastic stress state induced by internal pressure and superimposed over extremely high plastic ...

The term ‘shelf life’ is generally understood to be the duration of that period, between packing a product and using it, for which the quality of the product remains acceptable to the product user. An attempt to predict this period from data on the product, the pack and the distribution and storage conditions is appropriate where alternative packaging ...

Predicting Crack-Formation Life
Journal of Mechanical Engineering Science, 1979This paper discusses the parameters likely to influence the crack-formation life of components. In particular, the relationship between the fatigue life of plain and notched specimens is considered, and a mathematical model for predicting the crack-formation life of components is proposed.

Probability-based life Prediction
1995The estimation of the life expectancy of a structure is not a simple task. Many factors affect the life of a structure. These factors include design parameters, design safety factors, design methods, type of structure, structural details, materials, construction methods and quality, loads, maintenance practices, inspection methods, and other ...

Structural Safety, 1989
Abstract Fuzzy set theory is used to encode system uncertainty in a structural reliability analysis. The fatigue failure for joints is described by the common empirical relationship between the applied stress and the corresponding number of stress cycles resulting in a failure.

Predicting scientists’ participation in public life
Public Understanding of Science, 2012This research provides secondary data analysis of two large-scale scientist surveys. These include a 2009 survey of American Association for the Advancement of Science (AAAS) members and a 2006 survey of university scientists by the United Kingdom’s Royal Society.
