Abstract
In adhesive bonded joints, it is recommended to design the bonding region, which is the critical zone, so that the shear stress acts. In general, the peel stresses in the adhesive joints are primarily effective in causing failure. In simple overlap joints with tensile load applied, peel stresses occur in the overlap ends by the effect of rotation. When designing simple overlap joints, it is important to design so as to minimize the effect of peel stress. In this study, in order to investigate the effect of designing the overlapping ends of the bonded materials at different angles on the joint strength, simple overlap connection models with six different tip angles (90° , 75° , 60° , 45° , 30° and 15°) were created in Ansys finite element analysis program and nonlinear stress and failure analysis was performed under the applied tensile load of the joints. As a result of the analysis, it was seen that the bond strength increased in angled models compared to the reference model (90° end angle model). According to the reference model, a strength increase of 29.1% was detected in the 15° end angle model.
