“…On the strength prediction of bonded assemblies, two different lines of analyses were developed over the years: the strength of materials and fracture mechanics-based methods. The strength of materials approach is based on the evaluation of allowable stresses [10,11] or strains [12,13], by theoretical formulations or the FEM. The assemblies strength can be predicted by comparing the respective equivalent stresses or strains at the critical regions, obtained by stress or strain-based criteria, with the properties of the structure constituents.…”

The structural integrity of multi-component structures is usually determined by the strength and durability of their unions. Adhesive bonding is often chosen over welding, riveting and bolting, due to the reduction of stress concentrations, reduced weight penalty and easy manufacturing, amongst other issues. In the past decades, the Finite Element Method (FEM) has been used for the simulation and strength prediction of bonded structures, by strength of materials or fracture mechanics-based criteria. Cohesive-zone models (CZMs) have already proved to be an effective tool in modelling damage growth, surpassing a few limitations of the aforementioned techniques. Despite this fact, they still suffer from the restriction of damage growth only at predefined growth paths. The eXtended Finite Element Method (XFEM) is a recent improvement of the FEM, developed to allow the growth of discontinuities within bulk solids along an arbitrary path, by enriching degrees of freedom with special displacement functions, thus overcoming the main restriction of CZMs. These two techniques were tested to simulate adhesively bonded single-and double-lap joints. The comparative evaluation of the two methods showed their capabilities and/or limitations for this specific purpose.

“…In order to assess failure within the adhesive, a failure criterion is needed. The suitability of different failure criteria for adhesives in single lap joints was studied by Harris and Adams [33], with the conclusion that for toughened ductile adhesive like the one used in the present study, the maximum principal strain is the best suited criterion. Further work carried out by Broughton et al [22] also showed that strain-based failure criteria give more accurate results than stress-based failure criteria for adhesively bonded joints.…”

“…Modern polymeric adhesives are usually highly nonlinear, causing linear elastic analysis to be insufficient. Furthermore, the eccentricity of many joint configurations results in large rotations early on in the loading 5,10,11 , necessitating the consideration of nonlinear geometric effects Therefore, geometric nonlinear effects due to large rotations and material nonlinearity are pivotal in predicting the strength of a joint. This paper will extend the previously created joint element to include these effects.…”

“…Others have done this by utilizing a Von Mises strain criterion or similar methods 5,11,21 . For the current formulation, it was assumed that the bulk adhesive tensile specimen strain and the adhesive layer strains were linearly related to each other through the equations …”

Enhanced finite elements are elements with an embedded analytical solution that can capture detailed local fields, enabling more efficient mesh independent finite element analysis. In earlier research, this method was applied to adhesively bonded joints. The adherends were modeled as composite Euler-Bernoulli beams, and the adhesive layer was modeled as a bed of linear shear and normal springs. The field equations were derived using the principle of minimum potential energy, and the resulting solutions for the displacement fields were used to generate shape functions and a stiffness matrix for a single bonded joint finite element. In this study, the capability to model large rotations and non-linear adhesive constitutive behavior is developed, and progressive failure of the adhesive is modeled by remeshing the joint as the adhesive fails. The results obtained using this enhanced joint element is compared with experimental results.
