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

    Författare :Artem Kulachenko; Sören Östlund; Thomas Abrahamsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Travelling webs; skew tension profiles; mixed dynamic formulation; fluting; Other engineering mechanics; 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

    Sammanfattning : This thesis focuses on understanding the mechanical behavior of fiber-based materials by utilizing various modeling approaches. Particular emphasis is placed on their structural variability, anisotropic properties, and damage behavior. LÄS MER

  5. 4. Micromechanical Behavior of Fiber Networks

    Författare :Svetlana Borodulina; Mikael Nygårds; Artem Kulachenko; Susanne Heyden; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Network simulation; Mechanical properties; Fibers; Bonds; Paper properties; Damage; Microfibril angle; Torsion;

    Sammanfattning : Paper is used in a wide range of applications, each of which has specific requirements on mechanical and surface properties. The role of paper strength on paper performance is still not well understood. This work addresses the mechanical properties of paper by utilizing fiber network simulation and consists of two parts.

  7. 5. Micromechanics of Fiber Networks

    Författare :Svetlana Borodulina; Artem Kulachenko; Sören Östlund; Mikael Nygårds; Pierre J.J. Dumont; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Network simulation; Mechanical properties; Fibers; Fiber-to-fiber bonds; Free fiber length; Number of contacts; Contact density; Paper properties; X-ray microtomography; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : The current trends in papermaking involve, but are not limited to, maintaining the dry strength of paper material at a reduced cost. Since any small changes in the process affect several factors at once, it is difficult to relate the exact impact of these changes promptly. LÄS MER
