   Single-lap joint. In order to determine the physical nature of stress distribution in adhesively bonded joints, the single-lap joints (SLJs) have been investigated by many researchers owing to its simple and convenient test geometry. The lap-joint problem is three-dimensional although it has a simple ://   Kayupov M, Dzenis, Y. Nonlinear finite element analysis of a single lap composite joint with a bond crack. In: Proceedings of the ASME mechanics & materials conference, Blacksburg, Virginia, USA, June 27–30, p.   Goland and Reissner () provided a well-known stress analysis of the single lap joint. They showed that adhesive peel stress is important in joint failure and also adhesive stresses are controlled by the normalized edge moment or edge moment factor k at the overlap ends arisen from transverse deflection of adherends. In their paper, Goland and Reissner decoupled the determination of edge The single-bolt, single-lap joint, shown in Figure (a), was used for the initial analysis on bolted joints carried out in this chapter, as extensive experimental and numerical results for this joint configuration were available from the literature [14–17].The joint geometry is based on the ASTM standard D /D M, [18].The geometric ratios, w/d = 6, e/d = 3, d/t = , were

Single lap joint tests, such as the ubiquitous lap shear test 30 , are relatively straightforward from the specimen preparation and testing perspective. However Stresses in a standard metal-to-metal adhesive-bonded lap joint are analyzed by a two-dimensional finite-element method and comparisons are made with previous :// /_Stress_Analysis_of_Adhesive-Bonded_Lap_Joints.

Panigrahi and Pradhan conducted the 3-D nonlinear finite element analysis to study the initiation and growth of the delamination in the adhesive of a composite double lap joint. Several researchers have conducted experimental tests to determine the strength and failure load of adhesively bonded :// Avoid in the single-lap joint causes a 60% increase in shear stress on the left edge, but it is only 40% for the stepped-lap joint. On the right side of the void, shear stress becomes four times higher in both joints. Thus, the stepped-lap joint has a better performance in reducing the effects of the void on shear stress field when compared to ?script=sci_arttext&pid=S Numerical analysis of the adhesive joints for single-lap adhesive joint involved determining the mean value of the destructive load as recorded in the experimental tests.
