The stresses in cemented joints, especially those by scarf and butt bondings, were studied photoelastically. The photoelastic models were made of epoxy resin and epoxy rubber, or epoxy resin and metal, namely, each material has respective elastic constant. Tests were carried out under tension and bending on a bar bonded with various angles. The results of experiment revealed that the stress concentrations were comparatively small on the scarf or butt bonding. The other result had revealed that the stresses on bonded boundary were not uniform under tension and bending, and that in the joints with a soft adhesive layer bonded to hard adherends, the stress concentrations were found on the and of bonded boundary with an obtuse angle, and in those with a hard adhesive layer bonded to soft adherends, found on the end of bonded boundary with an acute angle.
