• Thermal residual stress distributions on the interface and in the vicinity of the intersections of the interface and the free surfaces of bonded dissimilar materials are calculated using the boundary element method. Thermoelastic constant stress terms are calculated using Airy's stress function. The thermal residual stresses, when the thermoelastic constant stress terms are subtracted, show free-edge stress singularity. The values of the order of thermal residual stress singularity and stress distribution functions agree well with the theoretical ones calculated based on Airy's stress function. It is shown that the thermal stress singularity disappears for certain ranges of wedge angles of a pair of materials, as predicted.
