“…These limitations were investigated by Ojalvo and Eidinoff [16] and Tsai et al [17]. Ojalvo and Eidinoff [16] investigated the effect of the adhesive thickness while Tsai et al [17] investigated the shear and normal deformations in the adherends.…”

“…Many authors have made various assumptions regarding the behaviour of the adhesive and the adherends to yield tractable differential equations, and have investigated the effects of various factors on the stresses in the adhesive layer and the joint strength [1][2][3][9][10][11]. These factors include adhesive plasticity [8], large deformation and rotation [10,12] satisfaction of the stress free requirement at the adhesive end [13], spew fillet [14], bondline thickness [15], etc. It has been shown that, in addition to the large deformation, adhesive plasticity is another important factor and needs to be taken into account in order to predict the joint strength appropriately.…”

Three-dimensional non-linear Finite Element Analyses (FEA) due to an in-plane loading have been performed to evaluate the out-of-plane normal and shear stresses over the overlap region of a Single Lap Joint (SLJ) on different surfaces. These surfaces have been considered as; (i) two interfacial surfaces between the adherends and the adhesive layer, (ii) the mid-surface of the adhesive layer and (iii) two surfaces beneath the surface ply of both the adherends adjacent to the adhesive layer. The critical locations of onset of adhesion, cohesion and delamination failures on the above mentioned surfaces of the SLJ have been determined using suitable damage criteria. A comparative study due to adhesion, cohesion and delamination failures in the SLJ with Fiber Reinforced Polymeric (FRP) composite adherends have been presented. The effects of simultaneous variations of the delamination positions on the out-of-plane peel and shear stress components have been studied by preembedding the delamination damages at the critical locations in both the adherends. It has been observed that the possibilities of onset of cohesion failures in the adhesive layer are higher compared to the adhesion and delamination failures. The detailed analyses showed that secondary peaks of out-of-plane stress components (σ z , τ yz and τ xz ) on the mid surface of the adhesive layer appeared at the locations closer to the delamination fronts due to preembedded delamination damages. The highest stress magnitudes on the overlap edge of the SLJ have been reduced significantly when the centers of the delamination damages are exactly aligned with the overlap ends of the joint. No significant variations of stress magnitudes have been noticed either when the delaminations are pre-embedded outside the overlap regions or when the delamination damages are completely entrapped within the overlap region.

“…Therefore, it is necessary to examine the strength characteristic of adhesive joints. Considerable amount of research has been carried out on the interface stress distributions and strengths of lap [1][2][3][4][5], butt [6][7][8][9] and scarf [10][11][12][13] adhesive joints subjected to static loadings. Some investigations have been carried out on the stress distributions in stepped-lap adhesive joints under static loadings [14][15][16][17].…”
