The stress and strain distributions in adhesive lap joints of hollow shafts with dissimilar diameters subjected to an axial tensile load are examined using an axisymmetric theory of elasticity. In the analysis, the joint is modelled as an elastic three-body contact problem and the hollow shafts and the adhesive are respectively replaced by finite hollow cylinders. In the numerical calculations, the effects of the ratio of Young's modulus of the adhesive to that of the shaft and of the thickness of the adhesive on the stress distributions at the interfaces in the joint are clarified. It is shown that the stresses in radial and circumferential directions become singular at the ends of the interfaces and the stress increases near the ends of the interfaces with a decrease of Young's modulus of the shaft and with an increase of the thickness of the adhesive.
