The boundary element method (BEM) has been used in various fields because BEM is convenient compared to FEM. BEM does not need an area integral in two-dimensional elastic problems without body forces, but in unsteady two-dimensional thermoelastic problems, the area integral is usually necessary. A method of transforming the area integral in BEM for two-dimensional unsteady thermoelasticity to a boundary integral has been recently reported [1]. However, a cell was used in a numerical example, and the time integral was carried out numerically. This paper shows that the time integral can be carried out analytically. The values of the stress discontinuities on the boundary are also clarified. In conclusion, it is shown that the same equation can be used in both the internal area and on the boundary.
