  2. 11. On Crack Dynamics in Brittle Heterogeneous Materials

    Author : Jenny Carlsson; Per Isaksson; Urban Wiklund; Cecilia Persson; Ralf Denzer; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering science with specialization in Applied Mechanics; Teknisk fysik med inriktning mot tillämpad mekanik;

    Abstract : Natural variation, sub-structural features, heterogeneity and porosity make fracture modelling of wood and many other heterogeneous and cellular materials challenging. In this thesis, fracture in such complicated materials is simulated using phase field methods for fracture. READ MORE

    Author : Juan José Espadas Escalante; Martin Fagerström; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering science with specialization in Applied Mechanics; Teknisk fysik med inriktning mot tillämpad mekanik;

    Abstract : This dissertation analyzes various mechanical properties of textile reinforced composite laminates.The dissertation is based on a total of six published works, which are essentially numerical, although experimental elements are available. READ MORE

  5. 13. Moisture-Induced Strains and Stresses in Wood

    Author : Sabina Huč; Staffan Svensson; E. Kristofer Gamstedt; Sigurdur Ormarsson; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 14. Biomechanical Analysis of Stress and Stiffness of New Load-Bearing Implants

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

    Abstract : 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.
