Download or read book Axial-load Fatigue Properties of 24S-T and 75S-T Aluminum Alloy as Determined in Several Laboratories written by H. J. Grover and published by . This book was released on 1953 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the initial phase of an NACA program on fatigue research, axial-load tests on 24S-T3 and 75S-T6 aluminum-alloy sheet have been made at the Batelle Memorial Institute and at the Langley Aeronautical Laboratory of the National Advisory Committee for Aeronautics. The test specimens were polished and unnotched. The manufacturer of the material, the Aluminum Company of America, has made axial-load tests on 24S-T4 and 75S-T6 rod material. The test techniques used the three laboratories are described in detail; the test results are presented and are compared with each other and with results obtained on unpolished sheet by the National Bureau of Standards.
