“…The fracture parameters were defined either experimentally or analytically and/or numerically by Mello and Liechti [19], Brunner et al [20], Choupani (2008) [21], Marannano et al [22], with account of the thickness and mechanical properties of the interlayer. A center crack in a weld strip between two identical materials under remote tensile loading was considered by Hao et al [23].…”

A plane strain problem for a crack in a thin adhesive elastic-perfectly plastic layer between two different isotropic elastic materials under the action of remote mechanical loading is considered. First, the problem is solved numerically using the finite element method. The stress distributions at the crack continuations and the J-integral values are found. Further, the analytical investigation of the formulated problem is performed. It is assumed that the pre-fracture zones arise at the crack continuations and the interlayer thickness is negligibly small in comparison with the crack length. Modeling the pre-fracture zones by the crack continuations with unknown constant normal and shear cohesive stresses applied to faces of the crack, the problem of linear relationship is formulated and solved analytically. The unknown pre-fracture zone lengths and cohesive stresses are derived from the condition of stress finiteness at the new crack tips and the yielding criterion of the interlayer material. The method of definition of the normal stress co-directed with the crack faces which is used in the mentioned yielding criterion is discussed. Expressions for the crack opening displacement and for the J-integral are obtained in an analytical form as well. The values of the J-integral obtained by means of the analytical method are in a good agreement with the results of the finite element solution.

“…Plane strain condition was assumed, to represent the constraint experienced by the thin adhesive layer confined between much stiffer adherends. The assumption of plane strain elastic modulus of the adhesive is also implicit in equation (13). The effect of any residual stresses is not considered in the analysis.…”

“…[4][5][6][7][8][9][10] provide a method of characterising material response over the entire range of mode mixities from pure mode I to pure mode II. The method used by Fernlund and Spelt [3] appears to be one of the few approaches [11][12][13] that do achieve this and in that respect it appears surprising that their technique has not been adopted more widely.…”

“…Results from analysis demonstrated that significant improvements could be achieved. The propagation of an interface crack subjected to mixed mode I/II was investigated by Marannano et al [56] for Al-Al bonded joints. The analytical strain energy release rate was compared with the FEA using the virtual crack closure technique (VCCT).…”

Some fastening techniques such as self-piercing riveting, mechanical clinching, and structural adhesive bonding are efficient joining methods which are suitable for joining advanced lightweight sheet materials that are hard to weld. The recent literature relating to fatigue behavior of such fastening joints and finite element analysis is reviewed in this paper. The recent development in fatigue behavior analysis of the fastening joints is described with particular reference to some major factors that influence the fatigue behavior of the fastening joints: failure mechanism, environmental effects, and hybrid joining techniques. The main methods used in finite element analysis of fatigue behavior of the fastening joints of sheet materials are discussed and illustrated with brief case studies from the literature.
