The stress fields near the apex in bonded dissimilar materials under surface tractions or thermal loading are represented by a linear combination of the singular solutions, the no singularity ones and the particular ones. In this paper, equations for each solution of the stress fields near the apex in bonded two quarter planes under surface traction w_0 and those under a uniform temperature change ΔT are theoretically derived, and the relationship between the solutions under w_0 and those under ΔT is investigated. For each solution, w_0 is expressed as a function involving ΔT and mechanical properties (Young's modulus, Poisson's ratio and thermal expansion coefficient) for the two materials. The thermal stresses caused by ΔT can be replaced by the stresses caused by w_0,and a method to obtain the thermal stresses from the stresses caused by w_0 is presented. In addition, the method is verified by the finite element method (FEM).
