Uni-Directional Axial Tension Fatigue Tests of Beryllium Copper and Several Precipitation Hardening Corrosion-Resistant Steels

Abstract

The results of notched tensile tests and smooth and V-notched fatigue tests are reported for beryllium copper, AM350 corrosion-resistant steel, and A-286 heat and corrosion resistant steel, and for open-hole notched specimens of 17-7PH corrosion-resistant steel. Cyclic loading tests also are reported for dimpled and riveted sheet specimens of AM350 steel which simulate typical single-lap riveted aircraft joints. Other tests are reported for 17-7PH steel specimens containing unloaded rivet-filled holes. The results of the tests are discussed from the point of view of a materials engineer in the aircraft industry. The need is discussed for additional useful information about the new materials now being developed and, also, about the less common older materials which are required now and then for specific designs.
