This paper deals with a two-dimensional stress analysis of a butt adhesive joint with rigid fillers in the adhesive subjected to a cleavage load. Similar adherends were replaced with finite strips, and an adhesive was replaced with a finite strip including rigid fillers. 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 on the stress distributions around the fillers and at the inter face were shown by numerical calculations. An experiment concerning the strains of adhesive was performed. The analytical result was consistent with the experimental result. It was seen that with an increase of the shift of location and size of fillers, the joint strength increased more than that of the joint without a filler. The stress singularity at the edge of the interface was discussed.
