Strength Evaluation of Scarf Joints Bonded with Adhesive Resin : Solid-Mechanics, Strength of Materials

Abstract

The strength evaluation of adhesively bonded scarf joints having adherends of the same or dissimilar metal was investigated both analytically and experimentally in order to accomplish a way of strength designing of adhesively bonded materials. The strain and stress distributions in the adhesively bonded joints were analyzed by means of the finite element method. The strengths were calculated on the basis of our criterion. The effect of the mechanical properties of adherends on the joint strength was examined. The deformation state and fracture mode of the joints having adherends of the same metal. It was predicted that the smaller the difference in the Young's moduli between the adherends, the greater the joint strength was.
