“…Their high strength coupled with light weight leads to their use wherever structural efficiency is at a premium. However, joints are always necessary to manufacture a large composite structure, among which bonded joints become increasingly common in automotive and marine field due to their ability to improve structural performance and help weight reduction [1][2][3]. Nevertheless, when load-carrying capacity is concerned, bolted joints are the most important methods of composite assembling especially in aerospace industry because of their high loadcarrying capacity and facility to assemble, disassemble, and repair.…”

Static tensile experiments and numerical simulations were carried out to study effects of hole perpendicularity error on mechanical performance of single-lap double-bolt composite joints. Hole tilting angle, varying from 1 to 4 degrees, and hole tilting direction to account for anisotropic properties of composite material were investigated. Progressive damage model (PDM) based on Chang-Lessard type criterion with an extension by Olmedo was created, which involved seven failure modes and made material properties be a direct function of predefined field variables. The model was implemented in ABAQUS/Standard using a UMAT subroutine. Good agreement was found when comparing numerical simulation results with experimental outcomes. In addition, the results demonstrate that, with increasing of hole tilting angle, damage is prone to arise and the load path of the composite bolted joints alters with changing of hole tilting direction, which result in severe stress concentration around the edge of hole and joint failure in advance.

“…Some works were interested in studying bonded joints with dissimilar adherends', although most of these studies used numerical and/or experimental approaches. Hazimeh et al 25,26 have studied the stress distribution in double-lap composite joints with dissimilar adherends under impact loadings using three-dimensional numerical analysis. Sawa et al 27 have performed a two-dimensional (2D) stress analysis under static loadings for the case of dissimilar substrates in single-lap joints.…”

Adhesive bonding is increasingly used in automobile, marine and aeronautical structures. The dynamic response of adhesively bonded joints is therefore a main concern. This paper deals with the harmonic response of single-lap joints. A closed-form analytical solution is derived to account for the case of joints with dissimilar substrates. The transfer functions predicted by the analytical model match well the transfer functions predicted by a two-dimensional finite element analysis, and so do the natural frequencies. The numerical and analytical models show that the natural frequencies are sensitive to the order of substrates. Mainly, fixing the end of the stiffer substrate leads to natural frequencies that are mostly higher than those which are obtained by fixing the end of the softer substrate.

“…Hazimeh et al 25 measured the impact responses of double-lap composite assemblies by the SHPB setup, in which they revealed that the shear strength and failure strain were sensitive to loading rate and the substrates' fiber orientation. Then Hazimeh et al 26,27 numerically exploited the stress distribution and heterogeneity in double-lap glass/PEEK composite joints tested with modified SHPB apparatus. In line with these papers, Saleh et al 28 concerned on the stress concentration in carbon/epoxy-braided composites joints.…”

Dynamic strength of adhesively bonded composite joints with similar and dissimilar assembled adherends

The effect of similar versus dissimilar assembled adherends, on the dynamic strength of single-lap, adhesively bonded composite joints is investigated. The assembled adherend materials include titanium, aluminum and composite. To this end, split Hopkins pressure bar is used to assess the strength of the joints at high loading rates. The tests show that the dynamic strength of the joints is influenced by the assembled adherend material stiffness, and the highest strength is achieved when using high stiffness adherend materials. Numerical results conclude that the increase in the stiffness of the assembled adherend material alleviates the stress concentration and promotes a more uniform distribution of stresses in the adhesive. The results of this study indicate that the selection of assembled adherend material should be accounted for while designing adhesively bonded composite joints.
