  3. 7. Process-Induced Local Material Variations in Finite Element Simulations of Cast and Fibre Reinforced Injection Moulded Components

    Författare :Johan Jansson; Kent Salomonsson; Jakob Olofsson; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The purpose of this thesis is to provide an overview of the methods used in the appended papers, in order to consider heterogeneous material properties in finite element simulations by using process simulations as input. The work deals with both injection moulded and cast components, and focuses on process-induced local material variations and their effect on component performance. LÄS MER

  4. 8. Finite Element Methods for Interface Problems

    Författare :David Samvin; Peter Hansbo; Kent Salomonsson; Jönköping University; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite Element Method; Interface; Embedded; CutFEM; Finita elementmetoden; Sprickor; CutFEM;

    Sammanfattning : This thesis focuses on computationally efficient methods for flow in fractured porous media. Two approaches are presented where the interface is embedded on the underlying finite element mesh. The methods allow for representation of the interface geometry from the underlying discretization and with discontinuities across the interface. LÄS MER

  5. 9. Structural impact on some physical properties of cellulose-based films

    Författare :Malin Nejström; Magnus Norgren; Håkan Edlund; Ida Svanedal; Bo Andreasson; Lars Evenäs; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Cellulose is a natural material that can be used both in its original form and as a building block for creating new types of materials. This work focused on regenerated cellulose (RC) and cellulose acetate butyrate (CAB) in which the hydroxyls on the cellulose backbone were substituted with ester groups. LÄS MER

  7. 10. Mechanics of Nanocellulose Foams : Experimental and Numerical Studies

    Författare :Prashanth Srinivasa; Artem Kulachenko; Laurent Orgéas; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : Nanofibrillär cellulosa (NFC) skum är en intressant klass av cellulära material med möjliga applikationer som sträcker sig från fordonsindustrin till biomedicin då det har unika och önskvärda mekaniska egenskaper. I ljuset av de senaste framstegen inom framställning av skum förutspås det tillämpas inom en rad olika områden, inklusive områden där dess mekaniska egenskaper är viktiga. LÄS MER
