Abstract
In the ordinary boundary element method for steady three-dimensional thermoelastic problems, the Galerkin vector is used to express the displacements, and Green's second identity is used to transform volume integrals into area integrals. In this paper the thermoelastic displacement potential is introduced for analysis. The displacements and stresses caused by temperature distribution are given by the derivatives of thermoelastic displacement potential. The method of superposition for solution is used to satisfy the complementary mechanical boundary conditions. The discontinuities of stress on the boundary are investigated by the analytic formulation. In order to investigate the accuracy of this method, steady thermal stress distribution in a cylinder is obtained. As a numerical example, the thermal displacement and thermal stress in a cup-shaped object are obtained.
