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 ln r or ln² r. The exact expressions for the corresponding singular stress field are presented. [ABSTRACT FROM AUTHOR]
