     in general, internal cells are required to solve thermo-elastoplastic problems using a conventional boundary element method (bem). however, in this case, the merit of the bem, which is ease of data preparation, is lost. the triple-reciprocity bem can be used to solve two-dimensional thermo-elastoplasticity problems with a small plastic deformation without using internal cells. in this study, it is shown that three-dimensional thermo-elastoplastic problems with heat generation can be solved by the triple-reciprocity bem without using internal cells. initial strain and stress formulations are adopted and the initial strain or stress distribution is interpolated using boundary integral equations. a new computer program is developed and applied to solve several problems.
