Singular Thermal Residual Stress Field near the Interface Corner of Bonded Dissimilar Materials

In this paper, a cooled composite interface corner consisting of two bonded dissimilar materials is considered as a plane problem. With the complex variable method, the thermal residual stress field is studied analytically. It is found that the regular stress term possesses the singularity either of lnr or ln2r. The exact expressions for the corresponding singular stress field are presented.
