Strength Evaluation of Adhesive Shaft Joints: (1st Report, Shafts of the Same Metal)

Abstract

The deformation and strength of adhesive shaft joints having shafts of the same metal and a coupling of various metals were investigated both analytically and experimentally. The strain distributions of joints under combined loads were analyzed by the finite element method. The strength of the joints was predicted by applying the strength laws to the adherend, adhesive layer and their interfaces. The effects of the coupling length and thickness on the joint strength were examined. The analytical strain distributions were in good agreement with the experimental ones. The results of strength prediction coincided approximately with the experimental ones. The effects of the Young&s modulus of the coupling on the joint strength were examined by varying the coupling metals. © 1988, The Japan Society of Mechanical Engineers. All rights reserved.
