  1. 1. Continuum modeling of paperboard for the mechanical response of converting processes

    Författare :Kristofer Robertsson; Hållfasthetslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Paperboard; Continuum modeling; Converting processes; FEM simulations; Finite strain theory; Damage modeling; Rate-dependent; Creasing and folding; Out-of-plane experiments;

    Sammanfattning : Paperboard is a thin and lightweight material made of cellulose fibers and it is an important component in packaging material where it provides stiffness and rigidity. The scope of this work is the development of continuum models, and its numerical treatments, for simulating the processes of converting paperboard into packages. LÄS MER

  3. 2. Elastoplasticity of Grey Cast Iron FE-Algorithms and Biaxial Experiments

    Författare :Hans E. Hjelm; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biaxial experiments; multiaxial elastoplastic behaviour; graphite flakes; FE-codes; hardening behaviour; graphitic grey cast iron;

    Sammanfattning : This thesis focuses on multiaxial elastoplastic behaviour of graphitic grey cast iron with the aim to provide physically appropriate and numerically reliable constitutive relations for use in FE-codes. To achieve this goal, this work is divided into three parts: Biaxial experiments are performed on thin cruciform specimens. LÄS MER

  4. 3. Self-assembly of magnetic particles

    Författare :Hauke Carstensen; Max Wolff; Vassilios Kapaklis; Björgvin Hjörvarsson; Benjamin Yellen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; self-assembly; tunable interactions; phase transition; ferrofluid; Fysik; Physics;

    Sammanfattning : Self-assembly is the spontaneous formation of larger structures from small building blocks. This process is driven and determined by the interactions between the constituents. LÄS MER

  5. 4. X-ray Absorption Spectroscopy on Nano-Magnet Arrays and Thin Films : Magnetism and Structure

    Författare :Andreas Persson; Dimitri Arvanitis; Cormac McGuinness; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; self organization; nano-magnet; xmcd; exafs; peem; magnetism; Surfaces and interfaces; Ytor och mellanytor; Magnetism; Magnetism; Materiefysik; Physics of Matter;

    Sammanfattning : The magnetic and structural properties of nano magnet arrays and ferromagnetic thin films are investigated. Circular x-rays are used and extensive use is made in this Thesis of the X-ray Magnetic Circular Dichroism (XMCD) technique. By means of the XMCD magneto-optic sum rules the values of the orbital and spin moments are determined. LÄS MER

  7. 5. Synthesis and characterization of zeolite films and membranes

    Författare :Magdalena Gualtieri; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

    Sammanfattning : In this work, a seeding technique was used to synthesize films and membranes of FAU, LTA and MFI type zeolites. In the first part, hydrothermal growth was performed without organic template molecules, which resulted in template-free zeolite films and membranes. LÄS MER
