“…The hypotheses applied to the adhesive and substrate layers are not limited. This approach gives an opportunity to avoid infinite tangential stresses [13,14] at the corner points (which arise in a rigorous solution of the problem under the assumption of absolute contact between the layers of the adhesive and the substrate), as well as to satisfy all boundary conditions. In [9,10] the infinite shear stresses at corner points are eliminated due to the elastoplastic work of the adhesive.…”

Predicting bond strength is the most common task in adhesion mechanics. To solve these problems, a contact layer model which describes the interaction of the substrate and adhesive layers, can be used. With the use of this model, which provides calculating the inhomogeneous stress-strain state of adhesive joints, a wide range of problems has been solved. Despite the fact that solutions, as a rule, are obtained in a closed analytical form, their use for processing experimental data can be difficult due to its complexity. In this regard a method that makes it possible to reduce the order of the resolving system of equations by introducing an integral contact layer connecting the adhesive layer and adjacent contact layers is proposed in this work. The application of this approach is demonstrated by the example of the most common adhesive lapped joint. As a result, the formulas for determining the parameters of the integral contact layer have been obtained. Comparison of the results obtained for the exact solution of the problem with the results obtained for the models with an integral contact layer is carried out.

“…Another approach is to allow the phenomenon of mixing. In the work [ 11 ], a Computational Fluid Dynamics (CFD) simulation concerning the flow of adhesive before curing and structural calculations after curing was performed. It has also been proposed to use a special nozzle for the simultaneous application of both adhesive layers.…”

Adhesive bonding are becoming increasingly important in civil and mechanical engineering, in the field of mobile applications such as aircraft or automotive. Adhesive joints offer many advantages such as low weight, uniform stress distribution, vibration damping properties or the possibility of joining different materials. The paper presents the results of numerical modeling and the use of neural networks in the analysis of dual adhesive single-lap joints subjected to a uniaxial tensile test. The dual adhesive joint was created through the use of adhesives with various parameters in terms of stiffness and strength. In the axis of the overlap, there was a point bonded joint characterized by greater stiffness and strength, and on the outside, there was a bonded joint limited by the edges of the overlap and characterized by lower stiffness and strength. It is an innovative solution for joining technology and the influence of such parameters as the thickness of one of the adherends, the radius of the point bonded joint and the material parameters of both adhesive layers were analyzed. The joint is characterized by a two-stage degradation process, i.e., after the damage of the rigid adhesive, the flexible adhesive ensures the integrity of the entire joint. For numerical modeling, the Finite Element Method (FEM) and cohesive elements was used, which served as input data to an Artificial Neural Network (ANN). The applied approach allowed the impact of individual parameters on the maximum force, initiation energy, and fracture energy to be studied.
