Available in PDF, EPUB and Kindle. Book excerpt: The object of this paper, which assumes the validity of Paris's equation, is to derive satisfactory estimates of the two constants C and m in the following conditions: (1) numerical process leading to the estimates of C and m is based on a rationale that takes into account the physical and statistical aspects of fatigue crack growth, and (2) the result of the fit compares favorably with existing procedures.
Download or read book Characterization of the Variability in Fatigue Crack Propagation Data written by DF. Ostergaard and published by . This book was released on 1983 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: The variability in fatigue crack propagation is studied through the analysis of 68 sets of replica constant amplitude fatigue crack growth data. Each of the a versus N data sets are fit to the integral of a crack growth rate equation through a finite integral optimization routine. The routine determines the best fit crack growth parameters of the crack growth rate equation. Through characterization of the variability in the crack growth parameters and utilizing statistical theory, the variability in the a versus N data is predicted. The finite integral method of obtaining the crack growth parameters was shown to very accurately reproduce the a versus N data. The variability in the crack growth parameters showed a strong linear trend, and a regression analysis on the parameters provided information to accurately predict the variability in the fatigue crack propagation data.

Available in PDF, EPUB and Kindle. Book excerpt: An experimental design method for determining statistically significant differences in fatigue crack growth rate data due to the influence of various test conditions (factors) is presented. This method is based on a completely randomized factorial design and a three-way classification Analysis of Variance (ANOVA) procedure. Although the example presented is for fatigue crack growth rate testing, this method is generic to any materials test program where comparisons of properties or behavior are made. The procedure allows decisions regarding these comparisons to be based on statistical tests of significance.

Available in PDF, EPUB and Kindle. Book excerpt: A simple-minded yet quantitative approach to assessing interlaboratory fatigue crack growth rate data is proposed. Seven sets of da/dN versus ?K data from six laboratories on nominally the same material and loading conditions in a cooperative test program sponsored by the Society of Automotive Engineers (SAE) are analyzed to illustrate this ad hoc approach. Each set of data is subjected to a standard first-order linear regression analysis based on the method of least squares. Three characteristics of the regression line [namely, the location of the "center" of the data, the slope, and the vertical half-width of the confidence band (for some specified level of confidence)] are used to define a composite measure of the closeness of one regression line to another. To illustrate the benefit of a statistically sound interlaboratory test program, the single-specimen SAE data are supplemented with fictitious replica data for the application of an interlaboratory data analysis procedure first proposed by Mandel (ASTM Standardization News, Volume 5, No. 3, 1977, p. 17). "New" information based on the ad hoc approach of this paper and Mandel's method of interlaboratory data analysis is discussed in the context of other work on fatigue crack growth rate data analysis and the economic aspect of engineering testing.

This book was released on 1985 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based upon available data, a detailed statistical analysis has been made of the fatigue crack growth process. Much has been learned about this process including it's history dependence, and the class of acceptable cumulative distribution functions of the time for a crack to increase a specified amount. Two potential probablistic models have been suggested and an initial investigation has been carried out. A methodology has been suggested for adaptive updating of a model of cumulative damage based upon service information to improve the accuracy of maintenance procedures to achieve a prescribed reliability. Based on the data, the effect of increase in length on the fatigue life was investigated. It was found that the weakest link idea was not applicable as a model and an acceptable model was proposed.
