Life Prediction of Notched Components

Journal of Engineering Materials and Technology, 1995
In 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.

Predictive Sequential Life Testing

Biometrika, 1978
Sequential 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 ...

Accelerated Life Test and Life Prediction of an Electromechanical Actuator

2019 International Conference on Artificial Intelligence and Advanced Manufacturing (AIAM), 2019
This paper gives an accelerated test method for electromechanical actuator (EMA) and predicts its life based on Wiener process degradation model. According to the historical fault data and the FMECA analysis, we obtain that the key weak links of the electromechanical actuators are the electromagnetic clutch and the tachogenerator.

Predicting the Dimensions of Life Satisfaction

Journal of Gerontology, 1976
Taking multidimensional life satisfaction as the basic premise of this study, a four-equation multiple regression model was constructed for its prediction. The set of regressors included some conventional biographical characteristics, a number of activity variables, and three indicators of retirement experience.

Life Prediction of Seals

1998
Abstract : The Air Force Research Laboratory requires a method for predicting the relative life of O-rings produced by different manufacturers. O-rings manufactured to the same MIL-spec from different manufacturers usually use different material formulations. Differences in formulations can result in different properties as the O-rings age.

Life Cycle Assessment and Service Life Prediction

Journal of Industrial Ecology, 2014
Summary Models 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.

Predicting the Confidence of Passing Life Tests

IEEE Transactions on Reliability, 1977
In this paper we consider the problem of predicting the results of a fixed-length preliminary test. Formulae of this s-confidence are presented for a wide variety of fixed-length reliability tests and preliminary test results. The -results also apply if the preliminary test consists of the initial portion of the reliability test itself.
