“…In this way, the joint has the maximum possible strength since the adhesives are at their maximum load bearing capacity. An alternative concept to the mixed adhesive joint is to profile the adherends or to vary the glueline thickness [41][42][43][44][45][46][47]. The analytical model of Raphael is rather simplistic since it only looks at the shear stress of the adhesive and ignores several important aspects such as the stress free condition and the variation of the adhesive stress through the thickness.…”

“…With the optimum profiles of the adherends, lap joints can be made where shear stress in the adhesive layer is constant which increases the load carrying capability of the adhesive. 19 Optimization procedure, in order to arrive at the optimum notches in three-dimensional (3-D) elasticity problems, is recommended by the application of fade-away law. 20 Through-thickness shape optimization method is presented to minimize the elastic stress concentration in adhesive lap joints.…”

The entitled technical subject in its comprehensive and broadly viewed study is presented by stating that the prevailing glass fiber–reinforced plastic composites play a vital role in replacing the metallic structures in automotive, aerospace, and marine applications and their more usage necessitates the better understanding of such structure’s damage and effective repair practices of the same. In the course of repairing the composite structures, optimum usage of patch material helps to maintain the original strength, eliminate “over design,” and reduce contribution to the substantial performance change of original structure. Optimum usage of repair material brings down the significant percentage of mass and repair cost. In order to apply the concept of optimum patch shapes over actual structures, it is important to design such effective shapes which are equivalent to the conventionally proven repair designs in strength perspective. This technical paper describes one of such ways to design the optimum patch shape using finite element analysis (FEA) tool and in comparison with one of the conventional repair practices, like circular patching, used circular, rectangular, square, elliptical and trapezoidal patch shapes, each of which has its own merits and demerits when compared to the other. But, none of them was arrived at in the perspective to use the minimum material to repair the damage. The object of this work is carried out in order to arrive at the optimum patch shape (minimum material in its in-plane direction) in repairing the damaged structure and it has been demonstrated using π/4 quasi-isotropic E-glass/epoxy specimen with hole using FEA. Moreover, the effectiveness of optimum patch shape design in “strength” and “load transfer efficiency” perspectives is experimentally proven and highlighted by the scope of repair material saving (36%) in repair practice by the usage of this optimized approach, as well.

“…Studies were conducted by researchers such as Gunthrop [9] and Kinloch [10] about lowering the high stress concentrations near the end of the bond line. A method for making the shear stress uniform along the bond length was presented by Cherry and Harrison [11]. This method was based on simple static equilibrium conditions.…”

MP 110422 unique mechanical behavior of suture joints. Stiffness, strength, and local stress distributions were predicted to assess variations in deformation and failure mechanisms. A unique homogeneous stress fields were observed throughout both the skeletal and interfacial components of the triangular geometry thus provided advantages in load transmission, weight, stiffness, strength, energy absorption, and fatigue over the rectangular geometry. Borgmeier and DeVries also studied the effect of the modification of the lap joint geometry by tapering the adherends. In these studies, unmodified and modified samples with tapered adherends were tested. They reported that tapering of the adherends reduced the rate at which shear stress increased as the bond termini were approached. This, in principle, results in a more uniform distribution of the shear stresses over the overlap region of the joint [14]. Afendi et al. [15] investigated the effect of scarf angle (θ = 45 0 , 60 0 and 75 0) on the strength of scarf joints of dissimilar adher
