For thermoelasticity and elasticity with a body force, the regular boundary element method
involves a domain integral. Special techniques have been devised to eliminate the domain
integral by either exact treatment, or approximation using radial basis functions. This paper
gives a unified presentation of these techniques. Body forces of gravity, centrifugal, gradient,
harmonic, and arbitrary types are investigated. In the approximation by radial basis function,
existing work is extended to include higher order basis functions of conical, spline, and …
