“…Moreover, due to the lack of corresponding standards, most of the researches on it still generally adopted the testing and calculation methods recommended by the standards for fiber-reinforced plastic composites as described above. Wannapa N et al 9 determined the mode II fracture toughness using the ENF testing method and data reduction method standardized in ASTM D7905. 7 The value was applied for a cohesive model in the numerical simulation of single-lap shear tests and validated by the numerical results.…”

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 extensive application of complex composite structures in engineering makes composite connections inevitable in structural design. Bolted connections can transmit higher loads, are more reliable and are easy to disassemble and repair, so they are widely used in composite connection structures (Li et al, 2021a, b;Wannapa and Uthaisangsuk, 2020;Zhu et al, 2020a, b). Sun et al (2002) used finite element analysis and experimental verification methods to explore the effect of composite bolt torque on the compressive strength of connecting holes.…”

PurposeThe influence of the number and arrangement of bolts on the tensile properties of bolted composite laminates was studied in the present study.Design/methodology/approachBased on the finite element model, the stiffness degradation method is used to simulate the damage evolution process for the failure of bolted composite laminates. Using ABAQUS finite element software combined with material failure criteria, the numerical calculation of the connection strength and failure mode of bolted composite laminates was carried out.FindingsThe results of the study show that the tensile strength of the composite laminates connected by three bolts is higher than that of the laminates connected by two bolts. And the arrangement of different bolts has a great influence on the failure strength of bolted laminates.Originality/valueBolted connection of composite laminates is a common problem in engineering practice. The effect of bolt arrangement and number on the strength of composite laminates is studied in this manuscript.

“…Dissimilar materials can be joined with various methods, ranging from mechanical fastening [39][40][41] to adhesive bonding. [42][43][44] Despite the applicability of these processes in industry, they have some drawbacks such as stress concentration, additional weights for mechanical joining and pollutant gases emitted by adhesives, inconvenient surface preparation procedures, long curing time for adhesive bonding. [45][46][47] Welding techniques are also used for the dissimilar assemblies.…”

“…59 To date, despite the practical advantages of direct bonding, researches on hot pressing without using any adhesive for dissimilar materials has been limited. Wannapa and Uthaisangsuk 44 successfully joined 5052 Al alloy with polybutylene terephthalate including 30% glass fiber reinforcement (PBT-30GFR) through adhesive bonding and hot pressing. To evaluate the static performance and failure behavior, singlelap joint (SLJ) specimens were fabricated.…”

Joining dissimilar materials to achieve lightweight design and energy efficiency has been increasingly popular. A joint formed by components of particle-reinforced metal and polymer matrix composite combines the merits of both materials. This paper is mainly focused on the research of the tensile lap shear and impact behavior of the dissimilar single-lap joints (SLJs) between SiCp/AA2124 composite and glass fiber-reinforced polypropylene (PP). The effects of out-of-plane loading applied from different surfaces of SLJs on impact responses are evaluated. Hot pressing technique is introduced to manufacture metal/polymer assembly without using any adhesive. The hole drilling effect is investigated with the idea that it may provide weight reduction and also increase the strength of the dissimilar SLJs. The results indicate that the dissimilar SLJs show more Charpy impact strength when the impact is performed on the metal-matrix composite (MMC). Mechanical properties of SLJs are adversely affected by a drilled hole in the MMC adherend.
