The dual reciprocity method has been successfully applied to boundary element analysis of the field problems to which the fundamental solutions are not available or difficult to implement. This paper is concerned with application of the dual reciprocity method to boundary element analysis of quasi-static coupled thermoelasticity. Time derivatives are approximated by a finite difference scheme, and the volume integrals in the boundary integral formulation are evaluated by means of the dual reciprocity method as the boundary-integral form with or without integral points in the domain. A new computer code is developed and applied to a couple of sample problems, whereby the usefulness and the computational aspects of the proposed solution procedure are demonstrated. Although emphasis is placed on the 2-D problems in this study, the present BEM method can be easily extended to 3-D problems.
