Abstract: The interpolation of 3D finite element displacement field is researched. The method of secondly subdivision meshes is proposed; it is based on Delaunay triangulation. According to this method, unitary model and partial remeshed model are firstly set up, the initial stress and displacement fields of unitary model are obtained by using FEM and back analysis. Consequently based on Delaunay triangulation, the method interpolates 3D finite element displacement field of unitary model. Then the interpolating results act as boundary displacement of partial model, based on which partial remeshed model performs finite element analyses. At last, this method is used in practical project; that proves that it can improve computational efficiency and it is feasible.

Key words: secondly subdivistion mesh, Delaunay triangulation, interpolation
