抄録

This paper deals with to make clear the mechanical properties such as apparent axial modulus of elasticity and strength, of the adhesive bonded butt joints of tubular type. Theoretical results on the apparent axial modulus calculated with the extended G. H. Lindsey's method, are compared to the results in experimental tensile tests of butt joints bonded with epoxy-polyamide adhesive. It is shown both in theoretical calculation and experiment that the apparent axial modulus of elasticity of joint fairly increases along with the increase of thickness of adhesive layer for the large Poisson's ratio. However, the modulus measured in the experimental test does not always coincide with the theoretical results as far as the thickness of adhesive layer is kept extremely thinner, because of the increase of unhomogeneity of the adhesive layer. Concerning of joint strength, joint fracture is brought when the strain in an adhesive layer that is comparatively thick, attains to a constant level. And the maximum shear stress in it also increases with the increase of adhesive layer.
