Inorganic substances such as portland cement also can be considered adhesives, in the sense that they hold objects such as bricks and beams together through surface attachment, but this article is limited to a discussion of organic adhesives, both natural and synthetic.
27, 28 The primary feature of JKR is to consider adhesive forces within the contact area, which can be considered as the summation of a Hertz contact area plus an area that arises due to interactive surface forces.
All parameters being considered, the adhesive coated surface proposes the best surface properties for efficient colorimetric microarrays.
The wide range of the joints' shear stiffness was simulated by either (i) assuming a perfect bond between glass and GFRP (i.e. neglecting the presence of the adhesive), or (ii) explicitly considering the adhesive, by means of using (ii.1) plane stress elements, or (ii.2) interface elements.
Finally the considered SMP adhesives and sealants are well suited for the chosen different substrates, although special attention should be placed on the glass GFRP joint as it is confirmed by statistical analysis.
An analytical model considering both adhesive joint effects and classic beam theory is developed for predicting the failure modes and stresses in each member of the sandwich structure.
The contact stresses in a bonded joint due to differential thermal expansions are calculated by considering the adhesive as an elastic rectangle confined by plates representing the adherends.
Then, a three-dimensional constitutive model is derived based on a four-elements model with an elastic series element by considering the adhesive to be a glassy polymer.
Concretely, the analytical model of axisymmetric shell bulging process considering tangential adhesive stress and the extended M-K model under non-planar stress state were established at first.
If we consider an adhesive joint as a multilayered medium, our model describes it as a surface with as many particles in each point of the surface as the number of layers in the medium (three layers for a simple lap joint and six layers for a double lap joint).
