“…e absence of a single value of G I from the experimental study makes the selection of an appropriate G I input data required for numerical simulation a very di cult one. e fact that the magnitude of the fracture energy of the adhesives is constant and independent of the adherent material and geometry when their failure surface along the adherent interface is completely cohesive [16]. Assuming that the simulated fracture surface of the C-M-C model is presumably cohesive, a propagation G I magnitude of 0.65 N/mm obtained in the monolithic C-C DCB sample is used instead.…”

The main contribution of the present paper is the determination of the mode-I fracture of metal-composite interface region for fibre metal laminates (FMLs). A hybrid DCB configuration is proposed to investigate the mode-I fracture between metal-composite interface using experimental and numerical approaches. A computationally efficient and reliable finite element model was developed to account for the influence of metal plasticity on the measured fracture energy. The results of the experimental and numerical studies showed that metal plasticity increases the fracture energy of the metal-composite interface as the fracture event progresses. The applied energy truly utilized to propagate metal-composite interface fracture was predicted numerically by extracting the elastic strain energy data. The predicted true fracture energy was found to be approximately 50% smaller than the experimentally measured average propagation energy. The study concluded that metal plasticity in hybrid DCB configuration overpredicted the experimentally measured fracture energy, and this can be alleviated through numerical methodology such as the finite element approach as presented in this paper.

“…The use of load-independent methods is, therefore, advantageous for faster rates. An analysis based on beam opening displacements and crack lengths has been developed and used successfully in the literature [11,12,17]. Depending on the toughness of the joint and the mass of the moving specimen arms, the effects of kinetic energy may become significant in the energy balance as the test rate is increased.…”

“…Both specimens have also been applied to high-rate fracture testing of adhesive joints [15][16][17]. For mixed mode I/II (see Section 3.6), the mixed mode flexure (MMF) also known as the single leg bend (SLB) test and the fixed-ratio mixed-mode (FRMM) are again popular for slow rates and can be used for faster rates also.…”

“…Brittle, untoughened adhesives may be insensitive to changes in rate. In mode II and mixed-mode I/II, reported rate sensitivities for various adhesives have ranged from being insensitive to test rate, for example, [17] to being somewhat positively rate sensitive, for example, [16]. As the fracture mechanisms are much more complex in mode II than mode I, the results are often more difficult to interpret.…”

Thermal-structural coupling nonlinear finite element analyses are conducted in this paper to determine three-dimensional stresses of a composite tee joint, which is formed when a right angled plate is adhesively bonded to a base plate at elevated temperature. The vonMises stresses of the adhesive layer of the tee joint with three different laminate stacking sequences viz. unidirectional [0] 8 , cross-ply [(0/90) s ] 2 , and angle-ply [(+45/À45) s ] 2 laminates have been evaluated when the tee joint is subjected to an out-of-plane loading through the right angled plate in addition to an elevated temperature applied at the undersurface of the base plate. The effects of laminate stacking sequence and temperature on von-Mises stresses have been investigated in this paper. The effects of the coefficient of thermal expansion and thermal conduction of the adhesive layer on von-Mises stresses have also been studied. Conclusions about the stresses of the composite tee joint with different stacking sequence, different coefficient of thermal expansion, and different thermal conduction of the adhesive layer are drawn.
