A posteriori error estimates for continuous/discontinuous Galerkin approximations of the Kirchhoff-Love plate
Artikel i vetenskaplig tidskrift, 2011

We present energy norm a posteriori error estimates for continuous/discontinuous Galerkin (c/dG) approximations of the Kirchhoff-Love plate problem. The method is based on a continuous displacement field inserted into a symmetric discontinuous Galerkin formulation of the fourth order partial differential equation governing the deflection of a thin plate. We also give explicit formulas for the penalty parameter involved in the formulation.
