In this paper, the singular stress field around the edge point in a bonded strip subjected to thermal loading is analyzed by body force method. Based on the numerical results, the effect of the beam geometry and material combination on the stress intensity factors are investigated. It is found that the singular stress σ_θ caused by heating or cooling may be positive or negative, depending on material combinations. It is also found that there is not a unique relationship between the stress singularity factor K and the eigenvalue λ.
