A contour integral is applied to the evaluation of the stress intensity factors at interface corners of bimaterial joints subjected to a uniform change in temperature. In order for the contour integral to work for the free-edge stress intensity factors, closed-form solutions for the stress and displacement fields near interface corners of bimaterial joints subjected to a uniform temperature change are derived. The derivation is based on the hypothesis that the two dissimilar materials, which are bonded along their common interface, experience identical rigid body displacements. Accordingly, the asymptotic displacements are continuous along the interface irrespective of the rigid body displace ments near the interface corner. A case study is carried out for a problem where the combination between the material properties and the geometry at the interface corner is such that the stresses at the interface corner are comprised of several stress fields of the form Hr
