A boundary element method based on dual reciprocity method (DRM) for steady-state thermal problem with inhomogeneous thermal conductivity is applied defect detections in three-dimensional solids. A defect in a solid can be regarded as an area whose thermal conductivity is zero. Therefore, defects in a solid may be detected by identifying the thermal conductivity distribution in the solid without considering the defects. BEM based on DRM can be successfully applied to identifications of thermal conductivity distributions of inhomogeneous media. Some numerical examples for three-dimensional solids are shown and the effectiveness of the present approach is demonstrated.
