TLDR
In this paper, the adhesive peel test has been investigated in both non-cracked and cracked configurations, and it was shown that initial failure was caused by the adhesive principal stresses driving a crack towards the interface with the flexible adherend.Abstract:
Large displacement finite element analysis and subsequent experimental work has been used to investigate the adhesive peel test; at this stage, only elastic behaviour has been considered. Both non-cracked and cracked configurations have been analysed, representing initial and continuous failure of the peel test. Analysis of the former indicated that initial failure was caused by the adhesive principal stresses driving a crack towards the interface with the flexible adherend. Investigation of the cracked configuration has shown that the amount of mode II loading at the crack tip is significant and is essentially independent of peel angle, load and adhesive or adherend modulus, only decreasing as the adhesive becomes incompressible. Failure (propagation) has been shown to occur at a critical applied bending moment for a particular adherend and adhesive, independent of peel angle. Further, the strength (load)'measured by the peel test is not proportional to the actual strength of the adhesive, a sma...read more

TL;DR: In this article, a theoretical analysis of the peeling of a thin elastoplastic film bonded on an elastic substrate is presented, where the moment-curvature relation for pure bending of an elastplastic beam under conditions of plane strain is derived and slender beam theory is used to analyze the deformation of the adherend.

Global yielding as a failure criterion for bonded joints
TL;DR: In this article, the authors present a technique based on a concept termed global yielding, which applies when a path of adhesive along the overlap region reaches the state in which it can sustain no further significant increase in applied load.

The adhesion of two elastic bodies with slightly wavy surfaces
TL;DR: In this paper, the stresses at the contact of two one-dimensional wavy surfaces in the presence of adhesion between them are found by the combination of the solution in the absence of affine adhesion due to Westergaard (1939, J. Appl. Trans. Arch. Mech. ASME 6, 49-53), with that for an array of collinear cracks due to Koiter (1959, Ing.

Crack tip finite elements are unnecessary
R. D. Henshell,K. G. Shaw +1 more
TL;DR: In this paper, it was shown that a singularity occurs in isoparametric finite elements if the mid-side nodes are moved sufficiently from their normal position to obtain a more accurate solution to the problem of determining the stress intensity at the tip of a crack.

Kuen Y. Lin,James W. Mar +1 more
TL;DR: In this paper, a hybrid crack element is constructed to properly account for the crack tip singularity, and the stress intensity factors and energy release rate for cracks in different bi-material continua are then calculated using the finite element method.

Relationship between mechanical properties of and crack progogation in epoxy resin adhesives
TL;DR: In this paper, a series of amine-cured epoxy resin adhesives in both the bulk material and adhesive joints has been studied as a function of the formulation of the resins and the conditions of testing using a linear elastic fracture mechanics approach.
