Abstract

This study is aiming at investigating the ultimate behaviors and curling influence on the ultimate strength in high strength aluminum alloys (7075-T6) single shear two-bolted connections using finite element analysis. The validation of finite element analysis for predicting the ultimate behaviors was verified through the comparison between previous test results and analysis predictions. Strength reduction due to curling occurrence was estimated quantitatively. Parametric analyses with extended variables were conducted and the conditions of curling occurrence according to end distance and edge distance were suggested. Finally, modified equation was suggested considering curling influence on the ultimate strength of aluminum alloys 7075-T6 bolted connections.
