The primary objective of this study is to investigate the effects of various parameters, such as bonding pressure, overlap length, adherend thickness, and material type, on the failure load and failure mode of joints with dissimilar materials.
While metal bonded joints generally fail at the adhesive, the final failure mode of all the tested bonded joints with dissimilar materials was delamination of the composite adherend.
This possibility, together with the possibility that some properties of the tube can be modified by functionalization or by proximity with dissimilar materials, makes this system an ideal candidate for many applications [14].
The capability of implants to deform at the right level, i.e. similar to the macroscopic mechanical response of the surrounding biological materials, is often associated with dissimilar microstructural deformation mechanisms.
The atomic thickness of graphene electrodes makes them a suitable platform to explore interfacial interactions with dissimilar materials and their impact on the rates and mechanisms of electrochemical reactions.
The ultimate tensile test strength (UTS) result, given in Figure 3, showed that the UTS of welds with dissimilar materials of strain hardened alloys of the 5xxx series (EN AC-AlMg9 according to EN 573-3) does not depend significantly on the travel speed and the plate thickness of the material.
The fracture processes and strain evolutions in the bondline were found to be symmetric for the joints with the same adherends, while the maximum strain and crack appeared first on the lap end of the lower yield strength adherend for the joints with dissimilar materials.
The present study examines the crack problems in a functionally graded material (FGM) whose upper and bottom surfaces are fully bonded with dissimilar homogeneous materials.
From mathematical point of view it is not a simple problem, since it involves mechanics of fracture applied not to a single solid body, but to two bodies with dissimilar material moduli and other properties common in the theory of continua, such as Poisson ratio, shear modulus and the inherent cohesive strength.
Even for dissimilar materials with thermoplastic composites, welding can be applied as thermo-melted fusion bonding methods [4,5].
