AbstractThe fatigue performance of composite joints is one of the major concerns for the extensive application of composites in aircraft structures. Accurate assessment of the fatigue life behaviour is crucial and valuable to this end. A wearout model was used to characterize the fatigue life behaviour of composite joint structures. The fatigue data used were selected from the open literature. A data fitting tool, which could deal with small fatigue data sample cases, was developed. The tool could accurately replicate the fitting parameters for S-N curves of single-piece composite cases and was used to study the fatigue life behaviour of adhesively bonded and bolted composite joint cases. Recommendations are made for improving the fatigue assessment capability in composite joint structures using the wearout model.
