“…Moreover, with the rapid development of high-strength adhesive, adhesive bonding can provide higher load bearing efficiency compared with mechanical joints, resulting in the dissimilar materials adhesively bonded structures being continuously applied in various engineering fields as shown in Figure 1. [1][2][3][4][5][6] However, fracture is one of the most important failure modes of adhesively bonded structures and often leads to catastrophic consequences. From the point of design, the understanding of fracture characteristic plays a key role in the reliable design of adhesively bonded structures.…”

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.

“…[1][2][3][4] Moreover, the application of fiber-reinforced composites leads to composite-metal adhesively bonded joints being adopted in engineering structure. [5][6][7][8] However, fracture of the adhesively bonded structures often leads to catastrophic failure. Based on this, the focus of the design of compositemetal adhesively bonded structures is the fracture of the bi-material interface.…”

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.

“…The development of the aerospace industry results in a constant increase in the complexity of various mechanisms and assemblies, which leads to an increase in their metal intensity [1,2]. One of the solutions to this problem is the use of lightweight materials with a high complex of special mechanical properties [3,4]. Cast magnesium alloys are one of the lightest structural materials, with a density of approximately 1.73 g/cm 3 ; their low density is approximately 25% that of steel and 60% that of aluminum [4,5].…”

Based on the results achieved in systematic studies of structure formation and the formation of multicomponent phases, a scandium-containing filler metal from system alloy Mg-Zr-Nd for welding of aircraft casting was developed. The influence of scandium in magnesium filler alloy on its mechanical and special properties, such as long-term strength at elevated temperatures, was studied by the authors. It is established that modification of the magnesium alloy with scandium in an amount between 0.05 and 0.07% allows a fine-grained structure to be obtained, which increases its plasticity up to 70% and heat resistance up to 1.8 times due to the formation of complex intermetallic phases and the microalloying of the solid solution. Welding of the aircraft castings made of magnesium alloy with scandium-containing filler material allows obtaining a weld with a dense homogeneous fusion zone and the surrounding area without any defects. The developed filler material for welding surface defects (cracks, chips, etc.) formed during operation on aircraft engine bodies makes it possible to restore cast body parts and reuse them. The proposed filler material composition with an improved set of properties for the welding of body castings from Mg-Zr-Nd system alloy for aircraft engines makes it possible to increase their reliability and durability in general, extend the service life of aircraft engines, and obtain a significant economic effect.
