Corrosion and Load Transfer Effects on Fatigue of Mechanically Fastened Joints.
Abstract
To provide a technical basis for formulating a reliable service life prediction methodology of aircraft structures, it is essential to understand and quantify the load transfer effect on the fatigue behavior of mechanically fastened joints. The work presented in this report aims at characterizing the fatigue behavior of mechanically fastened joints and identifying the load transfer effect. With tests of low, medium, and high load transfer specimens of 7475-T7351 aluminum alloy, the fatigue crack initiation and growth, and the fracture behavior have been investigated, and the load transfer effect has been defined quantitatively. The results are compared to those of a zero load transfer specimen, reported previously.
