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

    Author : Eric Linvill; Sören Östlund; Johan Tryding; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. 3-D Forming of Paper Materials

    Author : Eric Linvill; Sören Östlund; Artem Kulachenko; Leif A. Carlsson; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 3. Two-dimensional Nanocomposites Based on Cellulose Nanofibrils and Graphene Oxide

    Author : Hanieh Mianehrow; Lars Berglund; Aji Mathew; KTH; []
    Keywords : Cellulose nanofibrils; graphene oxide; orientation; reinforcement; oxygen barrier; bio-nanocomposite; moisture; molecular adhesion; interfacial shear strength.; Nanocellulosa; grafenoxid; orientering; förstärkning; syrebarriär; bionanokomposit; fukt; molekylär adhesion; skjuvhållfasthet hos gränsytan.; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Two-dimensional (2D) nanocomposites based on cellulose nanofibrils (CNF) and 2D nanomaterials are of interest as sustainable materials combining functional and structural properties. To achieve reinforcement effects from 2D nanomaterials, their orientation and dispersion state in the CNF matrix are important. READ MORE

  6. 4. On the in-plane mechanical properties of birch plywood

    Author : Tianxiang Wang; Magnus Wålinder; Roberto Crocetti; Bo Källsner; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Birch plywood; in-plane mechanical properties; load-to-face grain angle; failure criteria; size effect; moisture; Björkplywood; mekaniska egenskaper i planet; belastningsvinkel relativt ytfaneren; brott kriterier; storlekseffekt; fukt; Building Materials; Byggnadsmaterial;

    Abstract : Birch plywood has favorable mechanical properties that could be used in new types of connections for timber structures, and thus enable a substitution of the current system with steel plates. Such new connections could result in significant advantages in terms of environmental impact and economy as well as ease of prefabrication and mountability. READ MORE

  7. 5. Internal frost damage in concrete - experimental studies of destruction mechanisms

    Author : Katja Fridh; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tining; frysning; kallt klimat; frostskador skador; betong; materiallära; materialteknik; frost; ice formation; material technology; calorimetry; concrete; length change; upptining; fukt; beständighet; livslängd; forskning;

    Abstract : The aim of the study was to identify mechanisms acting at internal frost destruction of concrete. By 'internal frost destruction' is meant damage caused inside concrete that is moisture insulated from the surroundings, i.e. when no moisture exchange with the surroundings is possible during freeze-thaw.
