Thermal stress distribution and thermal strength were examined when butt adhesive joints with rigid fillers in an adhesive were in steady-state temperature distribution. In the analyses, the thermal stress distribution in the adhesive was given using the two-dimensional theory of elasticity in the case where adherends composed of the same size and the rigid material were kept at a constant temperature and the side surfaces of the joint were surrounded with fluid of a different temperature. Numerical calculations showed that the thermal stress was tensile near the end of the interface between the adherend and the adhesive and around the interface where the filler was included underneath, the thermal stress concentrated at the periphery of the filler, and large concentration of thermal stress was generated when the filler size was large. Photoelastic experiments were carried out, and the analytical results were consistent with the experimental ones.
