  1. 1. Elasticity of Cellulose Nanofibril Materials

    Författare :Gabriella Josefsson; E. Kristofer Gamstedt; Karin de Borst; Uppsala universitet; []
    Nyckelord :Cellulose nanofibrils; Elastic properties; Micromechanics; Composites; Engineering science with specialization in Applied Mechanics; Teknisk fysik med inriktning mot tillämpad mekanik;

    Sammanfattning : The demand for renewable load-carrying materials is increasing with increasing environmental awareness. Alternative sources for materials manufacturing and design have to be investigated in order to replace the non-biodegradable materials. LÄS MER

  3. 2. Creep aspects of softwood from the cell-wall level to structures

    Författare :Rhodel Bengtsson; E. Kristofer Gamstedt; Mahmoud Mousavi; Reza Afshar; Falk Wittel; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Creep; Solid Mechanics; Wooden Materials; Linear Viscoelasticity; Experiments; Materialvetenskap; Materials Science;

    Sammanfattning : This thesis addresses the intricate mechanical behaviour of natural materials, with a particular focus on wood. Despite millennia of use, understanding the mechanical behaviour of wood materials remains challenging due to their complex microstructures. LÄS MER

  4. 3. Moisture-Induced Strains and Stresses in Wood

    Författare :Sabina Huč; Staffan Svensson; E. Kristofer Gamstedt; Sigurdur Ormarsson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mechanosorption; multi-Fickian moisture transport model; orthotropy; rheology; three-dimensional mechanical model; viscoelasticity; wood; Engineering science with specialization in Applied Mechanics; Teknisk fysik med inriktning mot tillämpad mekanik;

    Sammanfattning : To design safe, reliable and durable timber structures subjected to varying natural outdoor or indoor climates, understanding the long-term behavior of wood when mechanically loaded or restrained to deform is crucial. The present thesis focuses on the numerical modeling of the long-term mechanical behavior of wood. LÄS MER

  5. 4. Biomechanical Analysis of Stress and Stiffness of New Load-Bearing Implants

    Författare :Jinxing Huo; E. Kristofer Gamstedt; Benedikt Helgason; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering science with specialization in Applied Mechanics; Teknisk fysik med inriktning mot tillämpad mekanik;

    Sammanfattning : Medical implants are essential products for saving lives and improving life quality. Nowadays, the demand for implants, especially biocompatible and personalized ones, is increasing rapidly to deal with factors like congenital malformations, aging, and increasing prevalence of cancer.

  7. 5. Structure and Mechanical Behaviour of Wood-Fibre Composites

    Författare :Thomas Joffre; E. Kristofer Gamstedt; Stéphane Avril; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Wood fibres have several advantages compared to man-made synthetic fibres: they have high specific stiffness, are renewable, relatively inexpensive, available in industrial quantities and biodegradable. However, to increase and diversify their utilisation, it is necessary to increase the understanding on what controls their mechanical properties. LÄS MER
