  4. 2. 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.

  5. 3. Realistic Package Opening Simulations : An Experimental Mechanics and Physics Based Approach

    Author : Eskil Andreasson; Blekinge Tekniska Högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymer; aluminium foil; semi-crystalline; progressive damage; Abaqus;

    Abstract : A finite element modeling strategy targeting package opening simulations is the final goal with this work. The developed simulation model will be used to proactively predict the opening compatibility early in the development process of a new opening device and/or a new packaging material. READ MORE

  6. 4. Chemical reactions in aluminium electrolytic capacitors

    Author : Ildiko Szaraz; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

    Abstract : Aluminium electrolytic capacitors are used in a wide variety of different applications. The aluminium electrolytic capacitor consists of two aluminium foils wound together and separated by special paper, which is impregnated with an electrolyte. READ MORE

  7. 5. Improved Adhesion Between Ethylene Polymers and Aluminium

    Author : Anders Strålin; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Adhesion between aluminium and polymers is important in a wide variety of applications. The aim of the present work was to improve adhesion in polyethylene- aluminium laminates by surface modification of aluminium. The treatments examined were hydration in boiling water and phosphatation by immersion in dilute phosphoric acid solutions. READ MORE
