Nowadays, fracture characterization of dissimilar materials adhesively bonded structures still generally refers to standards for fiber‐reinforced plastic composites. Moreover, the calculation methods of fracture energy release rate specified in these standards often lead to great deviation due to the differences in material properties and geometry. In this paper, dissimilar materials corrected beam theory with effective crack length (DM‐CBTE) method for calculation of mode II fracture energy release rate of dissimilar materials adhesively bonded structures was proposed. The differences in material properties and geometry as well as the effect of clamp were all considered. The experimental and J‐integral numerical analysis results showed that the maximum deviation of the GIIC calculated by the methods recommended in standard from the J‐integral result is 28% while that by the DM‐CBTE method is only 5%, which proved good feasibility of the DM‐CBTE method for evaluation of mode II fracture performance of dissimilar materials adhesively bonded structures.

“…The results demonstrated that the developed method could effectively characterize mixed‐mode and mode II dominated fracture of the hybrid‐material bonded interface. Qiao et al 23 presented an investigation on characterizing mixed‐mode fracture of the hybrid‐material bonded interfaces by proposed combined analytical and experimental approach under 4ENF loading. Quan et al 24 evaluated the mode II fracture behavior of CF/PEEK‐to‐aluminum bonded joints by the ELS method.…”

The investigation on fracture test methods for dissimilar materials adhesively bonded structures is urgent. In this study, three mode II fracture test methods for composite‐titanium adhesively bonded structures are experimentally and numerically studied. A manual inverse fitting method is adopted to obtain accurate cohesive models, and sensitivity evaluation of test methods is comprehensively conducted. The results show that GII of the experimental end‐notched flexure (ENF) test is nearly 20% greater than end‐loaded split (ELS). The effect of friction can be ignored, while all methods are highly dependent on the adherend's thickness, especially the maximum deviation of ELS that is 23.74%. In addition, the condition that the adherend with smaller flexural stiffness places outside the bending direction should be avoided to achieve mode II dominant possibly. In summary, the ENF test method with span length of 100 mm and small adherend's thickness is recommended for the mode II fracture test of the dissimilar materials adhesively bonded structures.

“…Several researchers have characterised the mechanical performance of multi-material combinations (particularly metal-to-composite) [4,5,6,7,8,9,10]. On one hand, some of these investigations reported the influence of adherent combinations on the joint strength [11,12,13,14,15,16] while on the other hand, others examined the fracture energy, J, for multimaterial combinations [17,18,19,20,21,22,23,24]. Some researchers studied the bond behaviour as a function of the adherent material properties and their combination with brittle and ductile adhesives [25,8].…”

The rate-dependent failure response of multi-material adhesive joints for three deformation modes is investigated. A combination of carbon fibre reinforced polymers (CFRP) and titanium alloy Ti-6Al-4V is employed. The experiments provide important information about the failure sequence of a multi-material adhesive joints, which depends upon the loading rate regime. This is the first time that dynamic fracture mechanics experiments are performed in multi-material adhesive structures. The observed experimental results suggest a rate-dependent failure sequence for mode I dominated fracture. Simulations of the experiments are used to predict and rationalise the failure performance of the multi-material adhesive joint. The numerical analysis highlighted the importance of the individual knowledge of the rate-dependent mechanical performance of adhesive and composite to fully understand the fracture sequence of multi-material joints under impact.
