“…So it is important to model and analyze the composite bonded joint to get the mechanical response and estimate the damage evolution. [6][7][8][9] An ideal structure would be designed without joints, since joints are potentially sources of weakness and additional weight. In practice however, upper limit to component size is generally determined by the manufacturing processes.…”

“…There are multiple loading methods in the tests and corresponding bonded specimens. The loading methods include peel off loading [1,4,6], shear loading, bending loading [17][18][19], compressive loading [15,20], biaxial tension [21], mix modes loadings [5], impact loading [12] and fatigue loading [7,22].…”

“…In the first loading phase, load is applied monotonically to a maximum load point. Then in the second step, load oscillates between maximum and zero values to simulate the fatigue loading condition [7]. From a numerical point of view, this method is close to the experimental loading procedure and hence avoids numerical instability.…”

“…Interface element model is another widely used methodology to model debonding process of crack tip in composite bonded joint ( Figure 3), which is implemented between adherend to evaluate fracture energy based damage in interface [4,7,12]. The load in simulation using interface element model is applied in two steps.…”

“…In energy based criterion, the energy release rates are derived as functions of strains (displacements) for all three fracture modes respectively [4,7,12,13,23,24]. And then the equivalent energy release rate is derived as a combination of energy release rates and compared with critical value to identify crack growth.…”

The bonded joints in composite structures is a challenging point in both research study and industry application.Compared with homogeneous and isotropic material, there is higher chance of stress concentration and intrinsic weak for this anisotropic structures. It is most common source of failure in structural laminates. So it is important to model and analyze the composite bonded joint to get the mechanical response and estimate the damage evolution. In this review paper, composite bonded joint are categorized based on bonded methods, materials, loading methods and failure modes. Multiple widely used adhesive bonded joint models including cohesive zone element model (CZM), interface element model, multiple point constraint model, kinking crack model, and repeating RVE model are introduced and discussed. To estimate the damage evolution in the bonded joint, a series of damage criteria have been developed including displacement based, stress based, energy based and modulus based damage criteria. Those damage criteria of bonded joint are also discussed and compared. This review work is important for the development of modeling of composite bonded joint in future.
