In this study, the singular stress field around the edge point of a bonded strip subjected to thermal loading is analyzed by the body force method. The intensity of the singular stress field is defined by a parameter called the stress intensity factor. Based on the numerical results, the effects of the strip geometry and material combination on the stress intensity factors are investigated. It is found that the singular stress σ on the interface caused by heating or cooling may be positive or negative, depending on the material combination. Also, a unique relationship between the stress intensity factor K and the eigenvalue λ does not exist.
