A analytical and experimental study of the deformation and strength of tubular shaft joints of carbon steel bonded with epoxy resin was conducted. The joints of two different types were studied changing the coupling shape ; one with a tapered coupling and the other with the straight coupling having a identical outer diameter with the shafts. The strain distribution calculated using the finite element method was in close agreement with experimental results. It was observed by the experimental stress-strain curve of the joint that the initial fracture occurred at the edge of a coupling before the joint was completely broken and that the initial cracking stress was much smaller than the final fracture stress. It was found that the effect of the dimension of internal diameter on the shaft strength was remarkable in the shaft with a tapered coupling but the effect was little in the shaft with a straight coupling, and the effect was more noticeable under the tensile load than the torsional load.
