| Abstract: | This paper proposes a Variational Boundary Integral Equation for time harmonic elasticity, using conjugate functions. A bilinear hermitian form for the variational formulation, as well as an a posteriori error indicator are proposed. The method does not involve hypersingular integrals in the finite part sense and preserves the symmetrical structures of equations. |
