  2. 1. A Study on Sandwich Structures : Development, Mechanical Characterization and Numerical Modeling

    Author : Samuel Hammarberg; Pär Jonsén; Jörgen Kajberg; Simon Larsson; Dan Zenkert; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultra-High Strength Steel; UHSS; Sandwich; Micro-sandwich; Hybrix; Modeling; Composite; Solid Mechanics; Hållfasthetslära;

    Abstract : Legislative demands force the automotive industry to reduce greenhouse gas (GHG) emissions. At the same time, crashworthiness must not be compromised. A ve-hicle’s GHG emissions, such as carbon dioxide, is dependent on its fuel consump-tion. Lowering the vehicle weight, reducing fuel consumption, will therefor reduce emissions. READ MORE

  6. 4. In-plane Compressive Response of Sandwich Panels

    Author : Anders Lindström; Dan Zenkert; Stefan Hallström; Leif Carlsson; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Sandwich; Finite Element Analysis FEA ; Fracture; In-plane compression; Other engineering mechanics; Övrig teknisk mekanik; Structural and vibration physics; Struktur- och vibrationsfysik;

    Abstract : The high specific bending stiffness of sandwich structures can with advantage be used in vehicles to reduce their weight and thereby potentially also their fuel consumption. However, the structure must not only meet the in-service requirements but also provide sufficient protection of the vehicle passengers in a crash situation. READ MORE

  7. 5. Wrinkling of sandwich panels for marine applications

    Author : Linus Fagerberg; KTH; []
    Keywords : wrinkling; local buckling; imperfection; stability; anisotropy; sandwich;

    Abstract : The recent development in the marine industry with largerships built in sandwich construction and also the use of moreadvanced materials has enforced improvements of design criteriaregarding wrinkling. The commonly used Hoff’s formula isnot suited for the highly anisotropic fibre reinforced sandwichface sheets of today. READ MORE
