| Abstract: | An explicit boundary type integral formulations of domain variables were presented for three dimensional initial strain problems using boundary element method. The domain variables were represented first by complete series of polynomial expansions, then the related domain integral were transformed into the boundary ones with the aid of the intrinsic correlation among the integral kernels as well as the high order fundamental solutions. The applicability of the formulation was discussed briefly. |
