This book was released on 2018-06-24 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental test procedures for the development of fatigue crack growth rate data has been standardized by the American Society for Testing and Materials. Over the past 30 years several gradual changes have been made to the standard without rigorous assessment of the affect these changes have on the precision or variability of the data generated. Therefore, the ASTM committee on fatigue crack growth has initiated an international round robin test program to assess the precision and variability of test results generated using the standard E647-00. Crack growth rate data presented in this report, in support of the ASTM roundrobin, shows excellent precision and repeatability.

Download or read book Design Against Fatigue Failure written by V. Weiss and published by . This book was released on 1975 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fatigue crack growth data in the low and intermediate stress range obtained from tests on 2014-T6 aluminum, Ti-6Al-4V and 250 grade maraging steel, and similar data on 7075-T6 and 2024-T3 aluminum available from other investigators were analyzed. This analysis led to the formation of a new model for estimating the threshold stress intensity factor range, which involves the concept of reaching the theoretical strength at the tip of the crack when the critically stressed volume becomes so small that it can no longer contain a defect. Fatigue crack propagation experiments were also conducted in the range of 10 to the minus 7 power and 10 to the minus 9 power in./cycle (2.5 x 10 to the minus 9 power to 2.5 x 10 to the minus 11 power m/cycle) at room temperature and 375 Hz. 7050-T73651 aluminum and D6ac steel *HRC 50) were tested in room air and dry and wet argon, whereas 2014-T6 aluminum and annealed D6ac steel were tested in room air only.

Download or read book Fatigue Data Handbook written by A. Buch and published by Trans Tech Publications Ltd. This book was released on 1998-03-17 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: This authoritative handbook presents an extensive compilation of data covering all important fatigue situations - fatigue strength of steels and other materials, notch- , size-, and mean stress effects, influence of temperature and corrosion, influence of special surface treatments, fatigue of structural elements and welds, aircraft fatigue, multilevel loading test programs, fatigue performance prediction etc.As is well known, fatigue investigations are often extremely time-consuming. The results of the tests depend upon numerous factors, and therefore handbook data must include all of the parameters which affect reported test results. The calculation of fatigue life and strength cannot be performed without having appropriate information concerning the specific fatigue situation. Nor can test programs be properly prepared without knowing the service conditions and the results of previous tests as, otherwise, the results obtained cannot be generalized. Information on component fatigue behaviour is of importance not only to machine designers but also to production engineers in charge of component manufacture, since processing strongly affects fatigue strength, and to maintenance engineers in charge of the operation and repair of cyclically loaded machine elements.

This book was released on 1976 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fatigue crack propagation and fracture parameters for 2.03-cm-thick compact specimens of an extra-low-interstitial Ti-6Al-4V alloy were measured at temperatures between 295 K (70°F) and 4 K (-453°F). Plane-strain linear-elastic and J-integral fracture toughness test results were in good agreement: the KIc values for this alloy decreased from 105 MN/m3|2 at room temperature to 54 MN/m3vb2 at 4 K, and a ductile-to-brittle fracture transition occurred in the range 125 to 76 K (-235 to -323°F). Despite this transition, the fatigue crack growth rates (da/dN) of this alloy remained temperature insensitive over the entire ambient-to-cryogenic range. These fatigue and fracture results are compared with data previously reported for a normal-interstitial Ti-6Al-4V alloy.

Available in PDF, EPUB and Kindle. Book excerpt: Fatigue-crack growth data for 2024-T3 aluminum was used to evaluate the accuracy of Forman's equation. Forman's equation was found to predict from one-third to twice the observed cycles to a given crack length when applied to multiple cyclic stress ratios. An alternative approach was developed, based on the observed data, which is applicable to analog or digital fatigue-crack growth prediction. Data acquisition based on constant increment of crack length has been found to yield inadequate definition of the crack-growth curve in the low-cycle range for the successful application of the method. An expression was developed which extends the application of the crack-closure concept to the entire range of cyclic stress ratio. An effective root-mean-square stress was defined which shows indications of good correlation with the magnitude of the crack-growth curves.
