CAMARGO, Liliana  and  DUQUE, Jairo. Implementing FEM-DtN for an incompressible material on an unbounded domain. Ing. Investig. [online]. 2010, vol.30, n.3, pp.124-130. ISSN 0120-5609.

This paper presents the implementation of the finite element method combined with Dirichlet-to-Neumann (D†N) mapping (derived in terms of an infinite Fourier series) for studying the solvability of an exterior problem arising in linear incomepressible 2D-elasticity. A reliable numerical experiment is also presented showing the accuracy of D†N mapping; only a few Fourier series terms were needed to get a good approximation to the solution. The stable Taylor-Hood element was used for finite element discretisation.

Keywords : mixed finite element method; Taylor-Hood element; D†N technique; linear elasticity; inf-sup condition.
