Abstract: | In the direct formulation of the boundary element method, body-force and thermal loads manifest themselves as additional
volume integral terms in the boundary integral equation. The exact transformation of the volume integral associated with body-force
loading into surface ones for two-dimensional elastostatics in general anisotropy, has only very recently been achieved. This
paper extends the work to treat two-dimensional thermoelastic problems which, unlike in isotropic elasticity, pose additional
complications in the formulation. The success of the exact volume-to-surface integral transformation and its implementation
is illustrated with three examples. The present study restores the application of BEM to two-dimensional anisotropic elastostatics
as a truly boundary solution technique even when thermal effects are involved. |
