Energy norm a posteriori error estimates for discontinuous Galerkin approximations of the linear elasticity problem
Artikel i vetenskaplig tidskrift, 2011
We present a residual-based a posteriori error estimate in an energy norm of the error in a family of discontinuous Galerkin approximations of linear elasticity problems. The theory is developed in two and three spatial dimensions and general nonconvex polygonal domains are allowed. We also present some illustrating numerical examples.
