Augmented Lagrangian Method for Thin Plates with Signorini Boundaries
Erik Burman, Peter Hansbo, Mats G. Larson
We consider -continuous approximations of the Kirchhoff plate problem in combination with a mesh dependent augmented Lagrangian method on a simply supported Signorini boundary…
Cut Bogner-Fox-Schmit Elements for Plates
Erik Burman, Mats G. Larson, Peter Hansbo
We present and analyze a method for thin plates based on cut Bogner-Fox-Schmit elements, which are elements obtained by taking tensor products of Hermite splines. The formula…
A Posteriori Error Estimates with Boundary Correction for a Cut Finite Element Method
Erik Burman, Cuiyu He, Mats G. Larson
In this work we study a residual based a posteriori error estimation for the CutFEM method applied to an elliptic model problem. We consider the problem with non-polygonal boundary…
Dirichlet Boundary Value Correction using Lagrange Multipliers
Erik Burman, Peter Hansbo, Mats G. Larson
We propose a boundary value correction approach for cases when curved boundaries are approximated by straight lines (planes) and Lagrange multipliers are used to enforce Dirichlet…
