Uni-Directional Axial Tension Fatigue Tests of Beryllium Copper and Several Precipitation Hardening Corrosion-Resistant Steels. M. H. Weisman, J. Mclill and T. Matsuda. Paper before Am. Soc. for Testing Materials, 2nd Pacific Area Nat’l Mtg., Los Angeles, Sept. 16-21, 1956. AST At Special Technical Pubn. No. 203, Fatigue of Aircraft Structures, 47-60; disc. 61-66 (1957).
Results of notched tensile tests and smooth and V-notched fatigue tests are reported for beryllium-copper, AM350, A-286 and 17-7PH. Cyclic loading tests also are reported for dimpled and riveted sheet specimens of AM350 which simulate typical single-lap riveted aircraft joints. Other tests are reported for 17- 7PH steel specimens containing unloaded rivet-filled holes. Purpose of tests was to determine effect of presence of certain types of notches and other stress concentrations on the static tensile strength and fatigue under conditions of uni-directional axial tension loading (stress ratio R equal to zero) over life range...
