  2. 1. Light-weighting Methodology in Rail Vehicle Design through Introduction of Load Carrying Sandwich Panels

    Author : David Wennberg; Sebastian Stichel; Per Wennhage; Ragnar Larsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sandwich panels; rail vehicle; lightweight; optimisation; carbody; Vehicle engineering; Farkostteknik; Construction engineering; Konstruktionsteknik; Construction materials; Konstruktionsmaterial;

    Abstract : Lightweight design in rail vehicles has been important for quite some time. Structures have been optimised to fulfill their purpose and cut unnecessary weight to reach allowable axle loads. Classically this is done by using steel, thin-walled structures, throughout the car body, or, alternatively, power-pressed aluminum profiles. READ MORE

  4. 2. Application of a Sandwich Construction on a Superstructure of a High Speed Ferry

    Author : Gaurav Ahuja; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; catamaran; pitch connecting moment; carbon fibre; natural frequency analysis; light weight structure; structural optimisation.; torsional moment; glass fibre; Sandwich construction; finite element analysis;

    Abstract : Usage of light weight materials has gained momentum in the marine market in the last few decades. This rise has lead to some ships using parts fabricated out of materials like glass and carbon fibre. READ MORE

  5. 3. 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

  6. 4. Reinforcement in Tailor-made Concrete Structures

    Author : David Fall; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tailor-made concrete structures; Steel fibre reinforcement; Automated production; Geometrically complex structures; Reinforcement alternatives;

    Abstract : In tailor-made concrete structures of complex geometries, the formability of concrete is an asset. To use this formability in load-bearing structures, the concrete needs to be reinforced. During the past century steel bars were used; however, in recent decades, alternative reinforcement methods have been introduced. READ MORE

  7. 5. Sustainability and Flexural Behaviour of Textile Reinforced Concrete

    Author : Natalie Williams Portal; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Life Cycle Assessment LCA ; sustainability; Textile Reinforced Concrete; TRC; facade elements; flexural behaviour; non-linear finite element analyses; structural tests;

    Abstract : Concrete reinforced with conventional steel is one of the most commonly used building materials, yet it has historically shown disadvantages in terms of durability and vulnerability to corrosion attack. Various remedial methods have been applied to overcome the shortcomings of this building material, such as increasing the concrete cover, which, however, leads to an increased self-weight of the structure.
