Abstract

This study compares the fatigue performance of several connections using theoretical and experimental methodologies to forecast the fatigue life of aviation connectors. To determine the matching yield strength and fatigue life of the four specimens, static tensile tests and fatigue tests were performed on four different types of porous single-shear lap joint specimens. Three example S–N models were produced in accordance with the fatigue life determined by the test. The effect that best fits the data is the three-parameter power function S–N model. When the fatigue life of the four different types of specimens is compared, it is clear that each type of specimen has excellent fatigue properties and can fatigue up to 3 × 107 times. In general, the high-lock bolt specimen has a longer fatigue life than the rivet specimen. The fatigue limit is reached by the high-lock bolt specimen, and the associated loading stress is higher than for the rivet specimen.
