“…The present paper focuses on stress-strain-based models but a mention should be made to fracture mechanics-based approaches [7][8][9]. For example, the resistance to crack propagation in an adhesive bondline can be quantified in terms of the critical energy release rate, G C .…”

“…The most common type of fracture test specimen is the double cantilever beam (DCB) type [1,2]. In this test, adherend beams (usually metallic) are bonded together with the adhesive, and the crack is propagated along the adhesive layer in the opening mode by pin loading at the beam ends (Fig.…”

An analysis of the crack tip stress field in DCB adhesive fracture specimens

The problem of a cracked adhesive bonded DCB-type fracture specimen has been analyzed using a hybrid stress model finite element analysis which incorporates an advanced crack tip element. Stresses in the near and far fields have been studied as a function of adherend/adhesive modulus ratio and adhesive thickness. The results are compared to monolithic systems with regard to the stress intensity factor and the localization of the singular stress domain associated with the crack tip.

“…Such test specimens may be valuable for the evaluation of the fracture toughness K~c for fatigue crack growth, for evaluating viscoelastic crack growth in an adhesive layer and for monitoring stress corrosion cracking [1][2][3][4][5][6][7][8][9][10]. Test specimen geometries have been developed in the shape of a double cantilever beam by Mostovoy, Crosley and Ripling [1], a rectangular cracked plate by Schijve and DeKoning [11], a circular ring-shaped specimen by Ahmad and…”

A test specimen has been developed that gives a constant value of the stress intensity factor in mode I under fixed displacement loading conditions. The test specimen is a double contoured cantilever beam specimen whose shape is derived from engineering beam theory. A final shape for a range of crack extensions where stress intensity is constant was established using a finite element analysis. It is believed that this specimen could be useful for many applications where a constant stress intensity factor is needed over a range of crack extension for constant displacement loading e.g. viscoelastic crack growth in an adhesive layer or stress corrosion cracking. Notation a = Crack length area x = Maximum crack length E = Young's modulus of elasticity G = Shear modulus h = Height of test specimen I = Moment of inertia k = Stiffness of one half of the test specimen K l = The stress intensity factor in mode I M = Applied moment P = Applied force t = Test specimen thickness u = Shape factor for shear deformation U = Potential energy v = Displacement in the y-direction = Constant defined in (5) 6 = Applied prescribed displacement v = Poisson's ratio
