Mixed hp-finite element method for linear elasticity with weakly imposed symmetry III: Stability analysis in 3D
arXiv:1006.0995
Abstract
The paper presents a generalization of Arnold-Falk-Winther elements for three dimensional linear elasticity, to meshes with elements of variable order. The generalization is straightforward but the stability analysis involves a non-trivial modification of involved interpolation operators. The analysis addresses only the h-convergence.
