“…Fracture mechanics have been used to solve the problem of the joint's strength in the case of brittle collapse with static [3,5,11] or fatigue loading [3,5,6,10]. The non-linear and viscoelastic adhesive's behaviour has been considered in references [6] and [11] to [15] and recently also a dynamic analysis has been performed [8,16]. Specifically, in references [7] and [17], emphasis has been placed on the positive influence of tapering at the adherends' end on the stress peaks in the adhesive layer from numerical and theoretical points of view respectively; if the adherends are partially tapered, the stress peaks become lower.…”

The paper analyses the problem of torsion in an adhesive bonded tubular joint. The constitutive, equilibrium and compatibility equations were used to obtain the stress field in the adhesive. The analysis confirms that the maximum stresses are attained at the ends of the adhesive and that the peak of maximum stress is reached at the end of the stiffer tube and does not tend to zero as the adhesive length approaches infinity.A special type of tubular joint can be produced by modifying the joint profile, thus ensuring that the stress field in the adhesive is constant and thereby optimizing the tubular joint for uniform torsional strength. This result is of considerable practical utility and makes it possible to produce adhesive bonded joints which are both lighter and stronger under torsion. Finally, some suggestions for the joint design are presented.

“…Miles and Reinhall [15] studied a model for the vibration behavior of a layered beam considering both the effects of shear and thinning of the adhesive layer. Ko et al [16], Lin et al [17] used FEM analysis to determine the free vibration behavior of adhesive joints. Saito and Tani [18] studied the natural frequencies and loss factors of adhesive joints subjected to both longitudinal and transverse coupled vibrations.…”

“…A similar job was done by Rao and Zhou [5] on tubular joints; they investigated, in addition, the effect of structural parameters and material properties of the adhesive on the modal loss factor and the resonant frequencies. Numerically, Ko et al [6] have established a finite element formulation based on isoparametric adhesive interface element where responses of each substrate and the adhesive layer were found separately. Later on, Lin and Ko [7] extended the latter analysis and applied it to a cantilevered stepped bonded plate.…”

The authors were concerned in this work in examining the influence of many mechanical and geometrical parameters on the mode shapes of vibration of a double-lap bonded joint. The parameters varied in this study were: adhesive Young's modulus, adhesive and adherents' thicknesses and overlap length. The substrates were made from steel; the adhesive is an epoxy resin. The study was carried out using ANSYS Finite Element software where the first ten modes were extracted. The results obtained from an experimental test conducted by the same workgroup were used to validate the numerical results. Based on the numerical parametric study, the results have shown a dominant influence of the substrates' thickness and the overlap length: the natural frequency increases remarkably with those two parameters. Moreover, the frequencies of the first ten modes were found to be very sensitive in increasing with the increment of either the adherents' thicknesses or the overlap length. On the other hand, the influence of the adhesive Young's modulus was found to be very slight on increasing the natural frequencies for all modes while the adhesive thickness was found to have quite no influence for the first couple of modes, with a slight decrement of frequency for higher modes. Finally, by setting the latter parameters to reference values, a unified parameter function of overlap length and adherent thickness was defined and approximated, and analytical relations for natural frequencies of the first ten modes were established.
