2. 1. Adaptive finite element methods for plate bending problems

   Author : David Heintz; Göteborgs universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; goal-oriented adaptivity; model adaptivity; discontinuous Galerkin; Nitsche s method; Kirchhoff plate; Mindlin-Reissner plate; Kirchhoff plate;

   Abstract : The major theme of the thesis is the development of goal-oriented model adaptive continuous-discontinuous Galerkin (c/dG) finite element methods (FEM), for the numerical solution of the Kirchhoff and Mindlin-Reissner (MR) plate models. Hierarchical modeling for linear elasticity on thin domains (beam-like) in two spatial dimensions is also considered, as a natural extension of the Bernoulli and Timoshenko beam theories. READ MORE

4. 2. Model Adaptivity in Elasticity

   Author : David Heintz; Göteborgs universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; finite element method; dimension reduction; a posteriori error; model error; model adaptivity; model error;

   Abstract : We consider model adaptivity in elasticity for dimensionally reduced forms, and shall treat different conceptual approaches. The basic idea, however, is to adaptively refine, not only the computational mesh, but also the underlying mathematical formulation. READ MORE
