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