This paper deals with a two-dimensional stress analysis of a butt adhesive joint with rigid fillers and circular defects (holes) in the adhesive subjected to a tensile load. Assuming that adherends are rigid, and replacing an adhesive with a finite strip including rigid fillers and circular holes, the analysis was done using the two-dimensional theory of elasticity in order to evaluate the joint strength. The effects of the location and size of rigid fillers and circular holes on the stress distributions around the fillers, circular holes and at the interface were shown by numerical calculations. For verification, photoelastic experiments were performed. The analytical result was in fairly good agreement with the experimental result.
