DUAL RECIPROCITY BEM APPLIED TO THE THERMOELASTIC PROBLEM WITH TEMPERATURE-DEPENDENT MATERIALS

摘要

This paper is concerned with a dual reciprocity boundary element method (DRBEM) for an effective solution of the thermoelastic problem in temperature-dependent materials. The fundamental solution for homogeneous materials is used in the integral equation formulation, and a domain integral arises in the resulting boundary integral equation. This domain integral is transformed into boundary integrals based on the dual reciprocity introducing a new set of radial basis functions. The details of the proposed DRBEM are presented, and a general-purpose computer code is developed for two-dimensional problems. Through discussion of the results obtained by the computer code for a few typical examples, the usefulness of the present DRBEM is demonstrated.
