Finite element approximations of symmetric tensors on simplicial grids in Rn: the lower order case
Jun Hu, Shangyou Zhang
In this paper, we construct, in a unified fashion, lower order finite element subspaces of spaces of symmetric tensors with square-integrable divergence on a domain in any dimensio…
A family of symmetric mixed finite elements for linear elasticity on tetrahedral grids
Jun Hu, Shangyou Zhang
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 tens…
Superconvergence of simple conforming mixed finite elements for linear elasticity on rectangular grids in any space dimension
Jun Hu, Shangyou Zhang
This paper is to prove superconvergence of a family of simple conforming mixed finite elements of first orderfor the linear elasticity problem with the Hellinger--Reissner variatio…
A family of conforming mixed finite elements for linear elasticity on triangular grids
Jun Hu, Shangyou Zhang
This paper presents a family of mixed finite elements on triangular grids for solving the classical Hellinger-Reissner mixed problem of the elasticity equations. In these elements,…
