“…Indeed, according to [8], the adhesive stress distribution along the overlap predicted by the ME models in the single-lap joint configuration is characterized by high stress gradients at both overlap ends for both HA and FGA joints. It is indicated that for FGA joints, and contrary to the HA joints, it is not always the case as highlighted by Stein et al [14]. As a result, the mesh was more refined at both overlap ends than at the middle of the overlap (Figure 9).…”

“…In this work, the adhesive peel modulus is then represented by the adhesive Young's modulus. These geometrical and material configurations are the same as those used in [8] inspired by [6,14]. The material and geometrical parameters are provided in Table 1 to Table 3.…”

“…Other choices could have been made to represent for the confinement of the adhesive layer between both adherends and subjected to out-of-plan tensile. The contribution of adherend out-of-plane stiffnesses in the adhesive peel modulus [32] or the plane strain adhesive Young's modulus instead of the adhesive Young's modulus as the adhesive peel modulus [33,14] are possible choice examples. Nevertheless, this discussion is out of the scope of this paper, even if it could be addressed with the provided models and results presented in this paper.…”

comparison between macro-element and finite element solutions for the stress analysis of functionally graded single-lap joints. (2019) Composite Structures, 215.Abstract -The interest in functionally graded adhesive (FGA) joints has been increasing in recent years. For example, FGAs offer the opportunity to optimize the strength of multimaterial bonded joints by locally tailoring the adhesive properties and without modifying the design of the adherends to be joined. The development of dedicated stress analyses to predict the stress distribution is then of the highest interest to control the strength of such joints. The Finite Element (FE) method is able to address the stress analysis of FGA joints but is computationally costly. Simplified stress analyses have then been developed. The objective of this paper is to assess the prediction of simplified stress analyses, solved through the macroelement (ME) technique, with respect to those of FE models. It is shown that the predictions of ME models are in a sufficient agreement with the FE models to be employed at a pre-sizing stage. The influence of the overlap length is then investigated by the means of the simplified 2 stress analyses. A noticeable result is the existence of an overlap length for which the adhesive peak shear stress is minimal, in the 1D-bar kinematics framework.

“…Nano-adhesive joints have been developed for use in the aerospace industry, and are important in many engineered components, although different nano-adhesives are used for different purposes [2,5,6]. Many studies of bonded lap joints for aerospace applications have been performed to improve our understanding of the mechanical properties of the joints [8,9,10,11]. Attempts have been made to use nano-technology to increase the stiffness of lap joints under rational load charges, to improve mechanical performance.…”

Experimental and numerical characterizations of nano-adhesivebonded joints typically used in aerospace applications are presented. First, samples of single-lap joints produced using a composite reinforced with carbon fibre fabric (2% graphene by weight), were analysed. Five samples were produced by injecting nanostructure particles in the epoxy resin and five are not (non-reinforced resin). Shear tests were performed to measure the resistances of the bonded joints, to assess the structural performances of the structures with and without the resin. Second, finite-element numerical models were applied based on experiments on adhesive joints; in particular a numerical simulation of the adhesive lap-joint model was performed using ANSYS software. Analyses were performed for the joints with unfilled and nanofilled adhesive, focusing on the cooling process during which adhesive single-lap joints are mainly generated. The experimental and numerical model results generally agree quite well. Graphene increased the stiffness of each lap joint under a rational load charge. The nanostructure adhesive increased the failure load, but this increase depended on various parameters, including adhesive structural features and the structures of the nanostructures produced. The reinforced adhesive nanostructure was found to decrease the weight.
