  1. 1. Fracture and Delamination in Packaging Materials : A Study of Experimental Methods and Simulation Techniques

    Författare :Md Shafiqul Islam; Sharon Kao-Walter; Christian Johansson Askling; Martin Kroon; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; packaging materials and laminates; shear test specimen; essential work of fracture; finite element simulation; optimization; tearing; peel; polymers; cohesive zone modelling;

    Sammanfattning : Packages are the means of preservation, distribution and convenience of use for food, medicine and other consumer products. The introduction of a new package-opening technique for a better opening experience requires additional prototype development and physical testing. LÄS MER

    Författare :Vedad Tojaga; Sören Östlund; Artem Kulachenko; T. Christian Gasser; Emanuela Bosco; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Staggered; Monolithic; Fracture; Constitutive modeling; Strong discontinuity approach SDA ; Simo-Reissner beam theory; Geometrically exact beam theory; Minimeringsalgoritm; Simo-Reissner balkteori; Icke kompatibla deformationsmode; Konstitutiva model; Solid Mechanics; Hållfasthetslära;

    Sammanfattning : This thesis summarizes seven appended papers dealing with: (1) The fracture of fibrous materials, e.g. LÄS MER

  4. 3. Realistic Package Opening Simulations : An Experimental Mechanics and Physics Based Approach

    Författare :Eskil Andreasson; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymer; aluminium foil; semi-crystalline; progressive damage; Abaqus;

    Sammanfattning : A finite element modeling strategy targeting package opening simulations is the final goal with this work. The developed simulation model will be used to proactively predict the opening compatibility early in the development process of a new opening device and/or a new packaging material. LÄS MER

  5. 4. Getting to grips with cartons : Interactions of carbonboard packages with an artificial finger

    Författare :Daniel Eriksson; Christer Korin; Sören Östlund; Örebro universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cartonboard packaging; Packaging mechanics; Packaging deformation; Manual handling;

    Sammanfattning : Packaging is an important part of most products in our modern world. It produces waste, but it also enables products to reach consumers safely and efficiently. Hence, the proper design of packaging is becoming increasingly important. Historically, cartonboard packages were designed for box compression strength. LÄS MER

  7. 5. 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
