The Influence of thickness of on mechanical behavior of butt-bolted joints is investigated via experiments and finite element analysis. A test is carried out on 8 sets of specimens, which are divided into 2 groups( A and B). The failure load and mode of bolt under tensile load is acquired via Group A specimens, and the influence of thickness of curved laminate on failure load and mode is obtained by Group B specimens. Based on the experimental results, 3D Finite Element Models (FEMs) are proposed to investigate the mechanical behavior of the specimens’ structure. Using Johnson-Cook, the material properties and damage criterion are defined to simulate the initiation and evolution of the bolt damage. The failure mode, the ultimate load and the calculated stiffness obtained with FEM are in good agreement with the test results. Furthermore, the damage initiation and evolution process are visualized with FEM, and the failure mechanism of butt-bolted joints is explained. According to the results of test and simulation, the stiffness, failure load and mode of the bolt is closely relevant to the thickness of curved laminate. There are four kinds of typical failure modes: bolt cross-section fracture (Type I), bolt head curling failure (Type Ⅱ), bolt head girding failure (Type Ⅲ), and curved laminate failure (Type Ⅳ). The influence rule of thickness of curved laminate on the mechanical properties of butt-bolted joints is obtained, and the “carpet map” about the failure mode versus the thickness of curved laminate, providing reliable engineering data and an efficient FEM method for the design of Ti-Al butt-bolted joints.
