A family of symmetric mixed finite elements for linear elasticity on tetrahedral grids
A family of stable mixed finite elements for the linear elasticity on
tetrahedral grids are constructed, where the stress is approximated by
symmetric H(\d)- polynomial tensors and the displacement is approximated
by - polynomial vectors, for all . Numerical tests are
provided.Comment: 11. arXiv admin note: substantial text overlap with arXiv:1406.745
