A family of H-div-div mixed triangular finite elements for the biharmonic equation

A family of Pk+22×2-PkH(divdiv)mixed finite elements on triangular grids is constructed for the biharmonic equation. For the H(divdiv)mixed finite element functions, both the stress tensor and its divergence have continuous normal components, σh⋅nand divσh⋅n, on each edge. The double divergence of t...
