The bonding of ceramics and metals is an effective method for applying ceramics to structural materials. In the previous paper, it was shown that high stress concentrations are induced only in the vicinity of the interface edge of the joint near the outer surface of a ceramic, and that the stress concentration can be reduced by modifying the shape of the ceramic. Using the thermoelastic-plastic finite element method, the authors investigate in the present paper how the thermal stress concentration and the shape of the plastic region in the metal are influenced by the size of both materials. It is found that the values of the stress concentration in the axial direction and the shape of the plastic region in the metal are changed by modifying the size of both materials, and that the plastic region in the metal develops from the bonding interface.
