“…Compared to the number of recent scientific publications concerning plane joints, with single or double lap [2][3][4][5][6][7][8][9], there are only a few theoretical works concerning the study of mechanical behaviour in adhesive assemblies with symmetry of revolution under tensile loading [10][11][12][13][14], subjected to torsion [15] or a harmonic axial load [16].…”

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

“…Because of the tight connection between the adhesive and the parent materials, a leak proof joint can be obtained. The strength of the adhesive connection also contributes to the torsional stiffness of the joint [11].…”

The goal of this master thesis is to realize and investigate leak tightness of joints produced by theelectromagnetic pulse (EMP) crimping process. This way of joining metals has gained more attention lately.With EMP welding, leak tight joints can already be achieved. However, the crimping process has somemajor advantages over EMP welding like the fact that more material combinations are possible and itrequires less energy. To realize the leak tightness, two kinds of sealing materials are used: O-rings andadhesives. The workpieces consist of an aluminium or stainless steel tube which is crimped on a solidaluminium mandrel with circumferential grooves in it. First, some preliminary tests are performed todetermine how much the tubes deform in the grooves. This deformation mainly depends on the appliedcharging voltage and the geometry of the groove. With this information, it is possible to estimate the amountof compression an O-ring would undergo when placed inside this groove. On other workpieces, adhesiveswill be applied. Several test procedures can be conducted on the parts to investigate leak tightness. Theresults of a helium test and a pressure burst test on the first test series conducted at the Walloon researchcentre CEWAC already showed that the use of O-rings can be effective.

“…However, they have not yet been researched in detail. Some papers have carried out on the composite joints [1][2][3][4][5][6][7][8][9]. However, few researchers have been performed on the stress distribution and the strength of composite cylinders which consist of low strength materials and high strength materials [1][2][3][4][5].…”

Epoxy-Steel composites have been used widely for lightening and strengthening mechanical structures. This paper deals with the stress analysis and strength estimation of epoxy-steel composite joint in which a hollow cylinder (epoxy) is fitted at the outside surface of a solid cylinder (steel) subjected to torsional loads. The interface stress distributions in the epoxy-steel composite cylinders under external torsion are analyzed using an axisymmetrical theory of elasticity as a two-body contact problem. In the numerical calculations, the effects of Young's modulus and the diameter of the solid cylinder on the interface stress distributions are examined. It is found that the shear stress increases as Young's modulus and the diameter of the solid cylinder decrease. A valid method for estimating the singularity is proposed. Using the interface stress distributions and analogous tests, the joint strength is predicted. In addition, the values of the joint strength were obtained experimentally. It is seen that a rupture initiates from the upper edge of the interface area when the torsion is applied to the upper end of the solid cylinder. For verification of the present analysis, FEM calculations are carried out. The numerical results are in fairly good agreements with the experimental results and the FEM results.
