    Författare :Per Wennhage; KTH; []
    Nyckelord :Optimization; acoustics; multidisciplinary; sandwich; composite; sound reduction index; railway vehicle;

    Sammanfattning : .... LÄS MER

  3. 2. In-plane Compressive Response of Sandwich Panels

    Författare :Anders Lindström; Dan Zenkert; Stefan Hallström; Leif Carlsson; KTH; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 3. Wrinkling of sandwich panels for marine applications

    Författare :Linus Fagerberg; KTH; []
    Nyckelord :wrinkling; local buckling; imperfection; stability; anisotropy; sandwich;

    Sammanfattning : 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. LÄS MER

  5. 4. Strength of Sandwich Panels Loaded in In-plane Compression

    Författare :Anders Lindström; Dan Zenkert; Stefan Hallström; Per-Lennart Larsson; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; sandwich; in-plane compression; energy absorption; debond; postbuckling; Engineering mechanics; Teknisk mekanik;

    Sammanfattning : The use of composite materials in vehicle structures could reduce the weight and thereby the fuel consumption of vehicles. As the road safety of the vehicles must be ensured, it is vital that the energy absorbing capability of the composite materials are similar to or better than the commonly used steel structures.

  7. 5. Structural Design of Laser-Welded Sandwich Panels for Marine Applications

    Författare :Hans Kolsters; KTH; []
    Nyckelord :Sandwich; Laser welding; Web; Core; Stiffness; Elastic Buckling; Ultimate strength; Finite element analysis; Mechanical testing; Optimisation.;

    Sammanfattning : In shipbuilding the replacement of stiffened platestructures by laser-welded sandwich panels offers considerableadvantages for production as well as vessel operation. In viewof reduced weight and space requirements an area of particularinterest is the incorporation of an adhesively bonded core bywhich the stiffness and strength can be substantiallyincreased, and thermal-acoustic insulation can be integrated.
