Abstract

Fretting fatigue is one of the mechanisms in the formation of cracks leading to multi-site damage in riveted lap joint assemblies in aging aircrafts. Relevant closed-form solutions for the two-dimensional elastic stress fields are adapted for reduced loading configurations relevant to aircraft lap joints. The stress field is combined with a multiaxial fatigue theory that combines strain-life with maximum normal stress to predict both the initiation site and life of fretting fatigue cracks. Increases in coefficient of friction and surface microslip reduce the number of cycles required to nucleate cracks.
