ASTM E739 - 10(2015) Standard Practice for Statistical

4.1 Materials scientists and engineers are making increased use of statistical analyses in interpreting S-N and -N fatigue data. Statistical analysis applies when the given data can be reasonably assumed to be a random sample of (or representation of) some specific defined population or universe of material of interest (under specific test conditions), and it is desired either to BEST PRACTICE GUIDE ON STATISTICAL ANALYSIS OF specific guidelines for analysing fatigue data obtained from tests on welded specimens. With the increasing use of fatigue testing to supplement design rules, an approach that is now encouraged in some Standards3-5, there is a need for comprehensive guidance on the statistical analysis of fatigue test

Fatigue Testing and Analysis ScienceDirect

Fatigue Testing and Analysis:Theory and Practice presents the latest, proven techniques for fatigue data acquisition, data analysis, and test planning and practice. More specifically, it covers the most comprehensive methods to capture the component load, to characterize the scatter of product fatigue resistance and loading, to perform the fatigue damage assessment of a product, and to ISO 12107:2012(en), Metallic materials ? Fatigue testing This International Standard is limited to the analysis of fatigue data for materials exhibiting homogeneous behaviour due to a single mechanism of fatigue failure. This refers to the statistical properties of test results that are closely related to material behaviour under the test conditions.

The re- sults of a rigorous statistical analysis have been used to estimate the probability of initiating a fatigue crack. Data in the literature were reviewed to evaluate the effects of size, geometry,' and sur- face finish of a component on its fatigue life. The fatigue

Mar 01, 1995 · A statistical model has been developed for estimating the effects of the various test conditions on fatigue life. The results of a rigorous statistical analysis have been used to estimate the probability of initiating a fatigue crack. Statistical and Probabilistic Analysis of Thermal-Fatigue Jan 17, 2014 · Therefore, statistical and probabilistic approaches have to be used to interpret the test data in order to implement the observations into new product designs. In this paper, the V-shape specimen test data are selected, analyzed and the scatter properties of the test data are fitted using several continuous probability distribution functions.
