Self-loosening process of a bolted joint consists of two distinct stages. The early stage self-loosening is due to the cyclic plastic deformation of the materials. The second stage self-loosening is characterized by the backing off of the nut. The current study concentrated on the investigation of the second stage self-loosening. It was found that for a given preload, there existed an endurance limit below which self-loosening would not persist. An "endurance diagram" concept was developed that can be used directly for the design and evaluation of the bolted joints. In addition, a three-dimensional finite element model was developed. The results from the finite element analysis reveal that the cyclic transverse load introduces a cyclic bending moment on the bolted joint. Micro-slip occurs between the contact surfaces of the engaged threads. The finite element simulation results agree favorably with the experimental observations.
