  1. 1. 3-D Forming of Paper Materials

    Författare :Eric Linvill; Sören Östlund; Artem Kulachenko; Leif A. Carlsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3-D forming; finite element method; constitutive model; moisture; temperature; biaxial; hydroforming; deep drawing; 3D formning; finita elementmetoden; konstitutiv modell; fukt; temperatur; biaxiell; hydroformning; djupdragning; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : Paper materials have a long history of use as a packaging material, although traditional paper-based packaging is limited in its shape, complexity, and design. In order to better understand the deformation and failure mechanisms during 3-D forming, two experimental studies of paper materials have been conducted. LÄS MER

  4. 3. Development of Finite Element Models for 3-D Forming Processes of Paper and Paperboard

    Författare :Eric Linvill; Sören Östlund; Johan Tryding; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3-D forming; constitutive model; moisture; temperature; hydroforming; deep drawing; 3-D formning; finitaelement; konstitutiv modell; fukt; temperatur; hydroformning; djup dragning; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : Paper materials have a long history of use in packaging products, although traditional paper-based packaging is limited in its shape and design. In order to enable more advanced paper-based packaging, various 3-D forming processes for paper materials have been studied. LÄS MER

  5. 4. 3-D Nautical Charts and Safe Navigation

    Författare :Thomas Porathe; Rune Pettersson; Åke Sivertun; Jan-Terje Bjørke; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; 3-D nautical charts; Mental rotations; safety at sea; vehicle navigation; 3D-sjökort; mentala rotationer; sjösäkerhet; fordonsnavigering; Information technology; Informationsteknik; Innovation och design;

    Sammanfattning : In spite of all electronic navigation devices on a modern ship bridge, navigators still lose their orientation. Reasons for this might be excessive cognitive workload caused by too many instruments to read and compile, navigation information that is displayed in a cognitively demanding way, short decision times due to high speed or fatigue due to minimum manning and long work hours.
