“…Alwar and Nagaraja [18] made a study by finite elements of tubular joining subjected to an axial load, taking into account the viscoelastic behaviour of the adhesive. They also showed that the viscoelastic behaviour of the adhesive makes it possible to predict a considerable reduction in the maximum stresses at the ends of the joint.…”

This paper presents a study of the stress analysis in cylindrical assemblies. For the present study we use a cylindrical assembly of two tubes. We write all the components of the stress field function of the s ð1Þ zz ðzÞ stress in the first tube and then we introduce these components into the potential energy formulation. Our method is a variational method applied on the potential energy of deformation. The model can predict the intensity and the distributions of stresses in the assembly. We can also analyse the influence of some geometrical or material parameters on the stress field. r

“…Many researchers have conducted studies on stress distribution in tubular adhesive joints subject to torsion to predict joint strength, given the geometry of the joint and the elastic material properties of the adhesive and adherend [1][2][3][4][5][6][7]. Recently, nonlinear analyses including the nonlinear properties of the adhesive have been developed to estimate the torque transmission capability more easily and accurately [8][9][10].…”

“…They obtained the stress distribution in the lap area, considering both the adherents and the adhesive to be elastic and the adherents to have a thin circular cross-section. Alwar and Nagaraja [13] solved the same problem, considering the adhesive to be a viscoelastic material. The shear stress distribution in tubular joints subjected to torsion has been obtained by Adams and Peppiatt [14].…”

Dynamic responses of adhesively bonded tubular joints subjected to a harmonic torsional load are evaluated. The adherents are assumed to be elastic, and the adhesive is taken to be a linear viscoelastic material. The in uence of the adherents and the adhesive properties on the joint response as well as on the shear stress amplitude distribution along the overlap is investigated. Furthermore, the effects of defects such as an annular void in the bond area on the dynamic response and shear stress amplitude distribution in the bond area are studied. The results indicate that, for the tubular joint geometries and properties investigated, the natural frequencies of the joint are little affected by the adhesive loss factor. The natural frequencies of the joint initially increase rapidly with increasing adhesive shear modulus. However, the natural frequencies asymptotically approach a constant value with further increase in adhesive shear modulus. The results further show that the natural frequencies of the joint may not be affected with the presence of a central void in the bond area.The distribution of the shear stress amplitude in the joint area was obtained. The maximum shear stress was con ned to the edge of the overlap for all applied loading frequencies. For the adhesive and adherent properties and geometries investigated, the maximum shear stress amplitude in the joint area was little affected by the presence of a central annular void covering up to 40 per cent of the oveplap length. The result showed that the shear stress amplitude distribution is more sensitive to the void location than to the void size. This was especially pronounced for voids located close to the edge of the overlap.A central void larger than 40 per cent of the overlap length may be detrimental or bene cial to the joint strength. This depends on the applied loading frequency. A central void reduces the system resonance frequency. This may take the system further away from the applied loading frequency or may bring it closer. A system excited closer to or further from its resonance frequency will develop a higher or lower shear stress amplitude in the bond area.
