Two-dimensional steady thermal stress without heat sources can be easily obtained by means of the boundary element method. However, if there are point or line heat sources within the region, it is difficult to solve these problem. This paper discribes a numerical method to solve the two-dimensional steady thermal stress under point and line heat generation. The temperature distribution can be obtained by the indricect boundary element method. The thermal stress is analyzed by means of the thermal displacement potential, the boundary element method and the method of superposition.
