  2. 1. Demagnetization Studies on Permanent Magnets : Comparing FEM Simulations with Experiments

    Author : Stefan Sjökvist; Sandra Eriksson; Hans Bernhoff; Mårten Grabbe; Uppsala universitet; []
    Keywords : Permanent magnet; demagnetization; simulation; FEM; Comsol Multiphysics; VAWT; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : In a world where money often is the main controlling factor, everything that can be tends to be more and more optimized. Regarding electrical machines, developers have always had the goal to make them better. READ MORE

  4. 2. Variation Simulation Customized for Composites by Including FEM Simulations of Orthotropic Lamina

    Author : Cornelia Jareteg; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geometry assurance; FEM; Composites; Shell model; Process variation; Method of Influence Coefficients; Monte Carlo; Orthotropic material; Manufacturing; Tolerance analysis; Variation simulation; Spring-in; Tolerance analysis;

    Abstract : The use of composite materials is increasing in many fields of production. Composite manufacturing, as well as other fields of production, suffers from uncertainties resulting in products that deviate from the specification. Geometry assurance is a common procedure used to keep the variations in product assemblies under control. READ MORE

  5. 3. Electrochemical machining: towards 3D simulation and application on SS316

    Author : A. A. Gomez-Gallegos; UK University of Edinburgh; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electrochemical machining; 3D Simulation; FEM; stainless Steel 316; surface Finish; Maskinteknik; Mechanical Engineering;

    Abstract : Electrochemical machining (ECM) is a non-conventional manufacturing process, which uses electrochemical dissolution to shape any conductive metal regardless of its mechanical properties and without leaving behind residual stresses or tool wear. Therefore, ECM can be an alternative for machining difficult-to-cut materials, complex geometries, and materials with improved characteristics, such as strength, heat-resistance or corrosion-resistance.

  6. 4. Computational Engineering Development and Implementation of Computational Methods for Structural Analysis and Design

    Author : Per Kettil; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CAD; simulation; FEM; optimisation; integration; modelling; object-oriented;

    Abstract : 'Computational engineering' (CE) is computation based on mathematical models for use in engineering design. CE can be used to study and optimise structures and processes in industry and other branches of society to utilise resources in the most effective way. Modelling, simulation, optimisation and visualisation are basic methods of CE. READ MORE

  7. 5. Mechanics and Failure in Thin Material Layers : Towards Realistic Package Opening Simulations

    Author : Eskil Andreasson; Sharon Kao-Walter; Gabriella Bolzon; Blekinge Tekniska Högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aluminium foil; FEM; LDPE; localisation; necking; polymer; progressive damage; semi-crystalline; simulation; virtual twin;

    Abstract : The final goal of this PhD-work is an efficient and user-friendly finite element modelling strategy targeting an industrial available package opening application.  In order to reach this goal, different experimental mechanical and fracture mechanical tests were continuously refined to characterize the studied materials.
