Abstract
The paper presents a generalization of Arnold-Falk-Winther elements for linear elasticity to meshes with elements of variable order. The generalization is straightforward but the stability analysis involves a nontrivial modification of involved interpolation operators. The analysis addresses only the h-convergence. In addition, numerical experiments for two dimensional cases are provided. Copyright © 2011 Society for Industrial and Applied Mathematics.
