P–S–N Curve Fitting Method Based on Sample Aggregation Principle
Journal of Failure Analysis and Prevention, 2019 Fatigue life tests play a central role in the design of mechanical systems, as the structural reliability estimation depends heavily on the fatigue strength of material, which need to be determined by experiments. The classical statistical analysis, however, can lead to results of limited usefulness when the number of specimens on test is small ...

PROBABILISTIC SPECIMEN PROPERTY-FATIGUE LIFE MAPPING AND P-S-N CURVE FITTING
International Journal of Reliability, Quality and Safety Engineering, 2013 Fitting P-S-N curve with small-size sample of fatigue test data is significant in engineering applications. Although several small sample-based P-S-N curve fitting methods have been developed, complexity in mathematics and/or the unrealistic assumption of the methods hinder their application seriously.

P-S-N curves with parameters estimated by particle swarm optimization and reliability prediction
2014 10th International Conference on Natural Computation (ICNC), 2014 Abstract The probabilistic characteristics of components cant be completely expressed by the S-N curve with parameters estimated by small number of specimens. Particle Swarm Optimization (PSO) is introduced to fit parameters with the incomplete test data, which can take advantage of the entire information of the specimens to obtain the globally ...

Backwards statistical inference method for P–S–N curve fitting with small-sample experiment data
International Journal of Fatigue, 2014 Abstract Based on the failure trajectory concept and backwards statistical inference technique, experimental programs are designed to fit P–S–N curve with a small number of test data. Underlying the program is a method to convert fatigue lives tested at different cyclic stress levels into the equivalent lives at an arbitrary stress level, by which a ...

Determination of probability distribution of fatigue strength and expressions of P-S-N curves
Engineering Fracture Mechanics, 1995 Abstract In the present study, new procedures are developed to determine the probability distribution of fatigue strength and the expressions of P-S-N curves. The fatigue test results of 16 Mn steel and the analysis show that the fatigue strength coefficient, the theoretical endurance limit and the fatigue strength at a given life follow the log ...

International Journal of Fatigue, 2016 Abstract The effect of stress ratio on statistical distribution of fatigue life of a unidirectional carbon/epoxy composite has been examined. Furthermore, a method for efficiently predicting a family of S–N curves with probability of failure as the parameter for any stress ratio of constant amplitude loading has been developed.

Fatigue & Fracture of Engineering Materials & StructuresABSTRACTThis study focuses on an improved statistical processing method for extremely small sample probabilistic S‐N (P‐S‐N) curve test data and proposes an improved backwards statistical inference method. By employing a quantile consistency principle, an equivalent large sample of fatigue lives can be obtained by congregating all test data, which ...
