  1. 1. Multiscale mechanical modeling of paperboard

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Gustav Boman; [2022]
    Nyckelord :Paperboard; micromechanics; multiscale; fiber; X-ray; RVE; Technology and Engineering;

    Sammanfattning : This thesis considers an investigation into the possibilities of creating a reasonably accurate multiscale material model for paperboard, with geometry based on X-ray scans of small paperboard samples. The modeling takes place in the software Multiscale Designer by Altair Engineering Inc. LÄS MER

  3. 2. Simulating a tensile test of a carbon fiber composite test specimen in ABAQUS

    Magister-uppsats, Institutionen för teknik och samhälle

    Författare :Ujjal kumar Saha; Adis Avdic; [2011]
    Nyckelord :composite material; ABAQUS simulation;

    Sammanfattning : This work aims at providing a numerical tool for the efficient design of the multidirectional carbon fiber reinforced composite material by means of finite element simulations. Abaqus/ CAE v 6.9-1 software has been used to establish a 3D model for simulation of the tensile test on the composite specimen. LÄS MER

  4. 3. Micropumps for extreme pressures

    Master-uppsats, Mikrostrukturteknik

    Författare :Stefan Svensson; [2009]
    Nyckelord :Micropump; Micromechanics; Paraffin; Actuator; High-pressure pumping; Steel membrane; Mikropump; Mikromekanik; Paraffin; Aktuator; Höga tryck; Stålmembran;

    Sammanfattning : The objective of this thesis was to improve a paraffin actuated micropump design, to be able to pump against extreme pressures (above 100 bar). This was accomplished by initially studying the membrane activation, using video capturing. LÄS MER
