“…The r* value for AV 119 was 72.839 MPa. The ultimate strain value (e*) for AV 119 was 0.548 [46]. Although the joints are normally subjected to tensile loading, but due to adhesive layer, the normal (r x ) and shear (s xy ) stresses along the x-axis and the peel stress (r y ) occur.…”

In this paper, the mechanical behavior of the Scarf Lap Joints (SLJs) bonded with adhesive under a tensile load was analyzed. The effects of adherend thickness at the interface stress-strain distributions of SLJs were examined. The stress-strain analyses were performed by Finite Element Method (3D-FEM). The 3D-FEM code was employed with Ansys (Ver.12.0.1). Experimental results were compared with the 3D-FEM results and were found quite reasonable. It was concluded that both experimental and 3D-FEM failure loads were increased with increased adherend thickness. The results indicated that the maximum failure loads were determined at t=8 mm in all joints. The analysis of the SLJs under tensile load showed that the stress and strain concentrations occurred around the edges of the joints.

“…In order to determine the effects of overlap length on the strength of a single lap joint, detailed FE study has been carried out to determine the magnitude and distribution of the stresses x , xy and eqv , similar as in [6]. Magnitudes of extreme values of analyzed stresses are given in the Table 2.…”

In this work the results of numerical stress analysis of single adhesive lap joints were presented. In the analysis both the linear-elastic and the elastic-plastic models of adherends materials were considered. Plastic deformation of adherends has a significant influence on the stress state in the adhesive layer. In the first part of the work the mechanical properties of adherends material obtained in experimental investigations were presented. In next part of the study the numerical model of joint was presented. The results of static analysis using the finite element method showed that in the case of joining materials with low value of yield stress the plastic deformation occurs in adherend at load much smaller than destructive force of the joint. In this kind of joints the plastic deformation of adherend has an influence on rapid stress increase in adhesive layer, in final stage of loading. This phenomenon causes a decrease of load capacity of single adhesive lap joints of elastic-plastic materials.

“…The used material model is Multilinear Isotropic Hardening von-Mises plasticity (MISO). VonMises yield criteria were used [19,20]. Physical and mechanical properties of adherent, adhesive, and patch (high-carbon steel) used in the construction of the non-linear finite element model are given in Table 1.…”

Accidents in the industry, especially in the field of aerospace, are quite common.Damages like tears cracks and holes occur especially when small sand particles present in the airfield collide with the body and wings of an airplane during takeoff and landing. This torn, cracked or pierced region should be repaired gently. Damaged parts are frequently small regions which repair is more suitable than complete replacement as workmanship; cost and time are an important concept in today's world. A gap occurs between the patches if double-bonded patches are used in the repair of the damaged parts. In this study, the region between patches in a joint with and without intermediate parts was modeled and its effect on strength was examined numerically and experimentally. The effect of patch thickness, overlap length, adherent thickness and gap length, on the strength of the joints with and without intermediate part was compared. The results show that the intermediate part does not have any influence on the strength of the lap joint such that double strap joints without intermediate part have higher failure Downloaded by [Cambridge University Library] at 07:06 14 August 2015 2load. Additionally, it is seen that the failure load decreased with increasing patch thickness and increased with the thickness of the adherent.
