The stresses in composite models with application to cemented joints, especially those by butt bonding, were studied by using the photoelastic and interferometric methods. The models were made of epoxy-poly sulfide copolymers. Tests were carried out under tension on a composite bar bonded at various interlayer breadthes. The results of experiments revealed that the stresses near the bonded boundary were not uniform and that in the joints with a soft adhesive layer, the stress concentrations were found on the end or center of bonded boundary in hard adherends, and they were almost reduced depending upon the decrease in the value of the breadth of adhesive layer. And in those with a hard adhesive layer, they were found on the end of bonded boundary in the hard adhesive layer, and they were increased depending upon the decrease in the value of the breadth of adhesive layer.
