“…Fig. 14 (a) shows the obtained xy stress profiles for the SLJ, in which τxy stresses peak at the overlap edges, and present smaller values at the overlap inner region [36,37]. This is caused by the adherends' differential deformation along the overlap.…”

Nowadays, any structure must have strength, robustness and lightness, which has increased the industrial interest and research efforts in adhesive joining, mainly in the improvement of strength and fracture properties of adhesives. Thus, in recent years, the use of adhesive joints in industrial applications has gradually grown, replacing some traditional bonding methods, since they have advantages such as reduced stress concentrations, reduced weight and cost, and ease of processing/manufacturing. In this work, the cohesive laws of three adhesives, Araldite ® AV138, Araldite ® 2015 and Sikaforce ® 7752, were obtained by the application of an inverse adjustment method between the numerical and experimental load-displacement curves (P-) of Double-Cantilever Beam (DCB) tests for tensile characterization and End-Notched Flexure (ENF) tests for shear characterization. Next, these laws were validated with experimental data of single-lap joints (SLJ) and double-lap joints (DLJ), using Abaqus ®. For the Araldite ® AV138 and Araldite ® 2015, in tension and shear, the triangular law accurately predicted the behaviour of the SLJ and DLJ. For the Sikaforce ® 7752, the triangular law did not suitably fit the experimental results. Due to its ductility, the Sikaforce ® 7752 could be modelled with a trapezoidal law for improved accuracy.

“…They showed that the tensile peeling and shear stresses at the bond free edges change significantly across the adhesive thickness. Vable et al (2006), used boundary element method to study stress gradient in adhesively bonded joints. Their work included both single-and double-lap joints.…”

In this paper, distribution of peeling stress in two types of adhesively-bonded joints is investigated. The joints are a single strap and a stiffened joint. Theses joints are under uniform tensile load and materials are assumed orthotropic. Layers can be identical or different in mechanical or geometrical properties. A twodimensional elasticity theory that includes the complete stressstrain and the complete strain-displacement relations for adhesive and adherends is used in this analysis. The displacement is assumed to be linear in the adhesive layer. A set of differential equations was derived and solved by using appropriate boundary conditions. Results revealed that the peak peeling stress developed within the adhesive layer is a function of geometrical and mechanical properties. FEM solution is used as the second method to verify the analytical results. A good agreement is observed between analytical and FEM solutions.
