N2 - In engineering applications, residual thermal stresses inside materials may lead to structural warp. Thus, accurate analysis of thermal stresses inside materials is of great importance for the assessment of structural integrity and performance. Emerging as an effective alternative of numerical tools, the boundary element method is well known for its notion that only the boundary needs to be discretised. However, the stress computations for interior points near the boundary will have numerical difficulty stemming from nearly singular integrals. This article presents a novel boundary integral equation that is fully regularized for computation of thermal stresses inside anisotropic materials. The veracity and applicability of the formulations derived are demonstrated by numerical examples at the end.
