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

    Författare :David Heintz; Göteborgs universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 2. Linear and Non-Linear Analysis of Plates and Shells by Use of Morley Finite Elements

    Författare :Ulrika Wendt; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; explicit dynamic formulation; adaptive methods; Shells Morley element; plates; Germain-Kirchhoff plate theory; finite element method; mixed plate formulation;

    Sammanfattning : The thesis deals with plate bending analysis and shell analysis in static linear and dynamic non-linear situations. The thesis contains two parts. In common for them is the use of the Germain-Kirchhoff plate theory, constant strain, constant curvature triangular plate elements and adaptive improvement of original solution. LÄS MER

  7. 5. Hygro-Elastic Deformation of High Pressure Laminates. A Macroscopic Analysis. Theoretical Modelling and Measurements

    Författare :Bijan Adl-Zarrabi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; numerical simulation; expansion; elastic deformation; moisture transport; orthotropic; high pressure laminate;

    Sammanfattning : Deformation due to environmental changes in moisture arises in many engineering problems of practical interest. The purpose of this work is to develop a theoretical model for the determination of moisture induced deformations in thin plates made of High Pressure Laminates. LÄS MER
