Available in PDF, EPUB and Kindle. Book excerpt: This paper shows how fatigue tests at elevated temperature solve many problems pertaining to aeronautical materials. Prolonged periods (5000 or 10 000 h) at 150 C (302 F) did not diminish the fatigue limit at 150 C (302 F) of the aluminum alloy 2618-T6. Consequently, the aerodynamic heating of airframes at Mach 2 does not reduce the fatigue limit of this alloy.

This book was released on 1962 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of compressive loads on structural fatigue at elevated temperatures are investigated using plain, notched, and welded Titanium 8Al-1Mo-1V, and PH 15-7Mo stainless steel coupon specimens. Specimens are subjected to Mach 3 spectrum test environment, including compressive loads. Fatigue life predictions are compared with spectrum teset results. The influence of prior stress-strain history on subsequent life is considered. Prediction methods are extended to include the compression range, and results notched specimens is determined analytically and experimentally. A variety of individual variable fatigue tests are performed at temperatures up to 900F.

Available in PDF, EPUB and Kindle. Book excerpt: Current Aeronautical Fatigue Problems contains the papers presented at the Symposium on Current Aeronautical Fatigue Problems, held in Rome in April 1963. The symposium is held with the purpose of reaching a fruitful and effective exchange of information on all aspects of fatigue problems in aeronautics. The main subjects covered in the symposium were: elevated-temperature effects, crack propagation and residual static strength, and structural fatigue testing. The specific topics discussed include the importance of non-linear interactions which affect creep and strength properties under variable stress and temperature; the factors affecting the fatigue life of a light alloy supersonic transport aircraft; the techniques of fractography applicable to crack propagation problems; and the use of ordered, cyclic, test loadings to represent the complex loading histories generated in service. Aeronautical engineers, materials scientists, physicists, and metallurgists will find the book invaluable.

Download or read book Fatigue Testing and Analysis of Results written by W. Weibull and published by Elsevier. This book was released on 2013-10-22 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fatigue Testing and Analysis of Results discusses fundamental concepts of fatigue testing and results analysis. The book begins with a description of the symbols and nomenclature selected for the present book, mainly those proposed by the ASTM Committee E-9 on Fatigue. Fatigue testing methods are then discussed including routine tests, short-life and long-life tests, cumulative-damage tests, and abbreviated and accelerated tests. Separate chapters cover fatigue testing machines and equipment; instruments and measuring devices; and test pieces used in fatigue testing. The factors affecting test results are considered, including material, types of stressing, test machine, environment, and testing technique. The final two chapters cover the planning of test programs and the presentation of results. Test program planning involves the statistical design of a test series; specification and sampling of test pieces; and choice of test pieces, testing machines, and test conditions. The chief purpose of most fatigue tests is the experimental determination of the relation between the endurance and the magnitude of the applied stress range for the material and the specimen under consideration, and final results can be condensed into a table, graph, or analytical expression.

Available in PDF, EPUB and Kindle. Book excerpt: A program was conducted to obtain complete stress versus number of cycles (S-N) curves for D6AC steel heat treated to an ultimate strength of 270 KSI. Tension-tension fatigue tests were conducted on notched and unnotched specimens at 75, 450, and 550 F for stress ratios of 1 and infinity. Tensile and stress rupture data were obtained in conjunction with the fatigue data.

This book was released on 2018-07-21 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: The major technology areas needed to perform a life prediction of an aircraft turbine engine hot section component are discussed and the steps required for life prediction are outlined. These include the determination of the operating environment, the calculation of the thermal and mechanical loading of the component, the cyclic stress-strain and creep behavior of the material required for structural analysis, and the structural analysis to determine the local stress-strain-temperature-time response of the material at the critical location in the components. From a knowledge of the fatigue, creep, and failure resistance of the material, a prediction of the life of the component is made. Material characterization and evaluation conducted for the purpose of calculating fatigue crack initiation lives of components operating at elevated temperatures are emphasized. Hirschberg, M. H.
