  1. 1. Mechanics of paper webs in printing press applications

    Detta är en avhandling från Stockholm : KTH

    Författare :Artem Kulachenko; KTH.; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Travelling webs; skew tension profiles; mixed dynamic formulation; fluting; TECHNOLOGY Engineering mechanics Other engineering mechanics; TEKNIKVETENSKAP Teknisk mekanik Övrig teknisk mekanik;

    Sammanfattning : The mechanics of paper is a difficult subject because paper is a unique material. It is very thin, flexible at bending, unstable in compression and stiff at tension. Dealing with paper we have to account for orthotropy and heterogeneities created during the manufacturing process. LÄS MER

    Detta är en avhandling från Div. of Solid Mechanics, Box 118, S-221 00 Lund

    Författare :Ingrid Svensson; Lunds universitet.; Lund University.; [2000]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydraulics; Mechanical engineering; Produktionsteknik; Production technology; experiments; damping; impacts; branch switching; dynamic stability; deflation; path following; vibrationer; akustik; vakuumteknik; hydraulik; Maskinteknik; vibration and acoustic engineering; vacuum technology;

    Sammanfattning : Popular Abstract in Swedish I denna avhandling analyseras olika typer av stabilitets fenomen. Först studeras det kvasi-statiska uppförandet av en elastisk struktur som lastas med en växande last. LÄS MER

  3. 3. Structural Analysis of Deep Composite Box-Type Components with application to a proprietary stabilising timber wall element

    Detta är en avhandling från Luleå tekniska universitet

    Författare :Seyed Rasoul Atashipour; Luleå tekniska universitet.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Sammanfattning : The stabilising wall element of the Trä8-system is a deep box-type beam/column element which is made of different types of timber composites including framing members of gluedlaminated timber (glulam) and sheathings of laminated veneer lumber (LVL). This element is used as a ―shear wall‖ in multi-storey buildings up to four storeys. LÄS MER

  4. 4. Weakening of Crack-tip Singularity due to Buckling of Thin Bodies under Tension

    Detta är en avhandling från LTH, Lund University

    Författare :Li Chong; Cong Li; Lunds universitet.; Lund University.; Malmö University.; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thin foils; Fracture; Buckling; Technology;

    Sammanfattning : When thin sheets containing a crack is subjected to tensile loading in the direction perpendicular to the crack surface out of plane displacement will occur in areas surrounding the crack. By this the stress state in the vicinity of the crack tip is changed and leads to a weaker crack tip singularity than the r-1/2 by linear elastic fracture mechanics. LÄS MER

  5. 5. Basic Testing and Strength Design of Corrugated Board and Containers

    Detta är en avhandling från LTH, Lund University

    Författare :Tomas Nordstrand; Lunds universitet.; Lund University.; [2003]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material technology; Materiallära; materialteknik; Produktteknik allmän ; Technology of other products; corrugation; compression; collapse; buckling; bending; box;

    Sammanfattning : Packaging serves a lot of purposes, and would be hard to do without. Packaging protects the goods during transport, saves costs, informs about the product, and extends its durability. A transport package is required to be strong and lightweight in order to be cost effective. LÄS MER
