    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

  4. 12. 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. Linear and Nonlinear Mechanics of Lattice Materials : Computational Modelling and Experiments

    Author : Danial Molavitabrizi; Mahmoud Mousavi; Kristofer Gamstedt; Haiyang Yu; Samuel Forest; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk fysik med inriktning mot tillämpad mekanik; Engineering science with specialization in Applied Mechanics;

    Abstract : Lattice materials are artificial materials made of repeating unit-cells. The internal architecture of these materials can be engineered for a specific application such as energy absorption, heat transfer, or acoustic damping. READ MORE

  7. 15. Pulsed laser ablation studied using digital holographic interferometry

    Author : Eynas Amer; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik;

    Abstract : Pulsed digital holographic interferometry has been used to investigate the plume and the shock wave generated in the ablation process of a Q-switched Nd-YAG (lambda= 1064 nm and pulse duration = 12 ns) laser pulse on a polycrystalline Boron Nitride (PCBN) target under atmospheric air pressure. A special set-up based on using two synchronised wavelengths from the same laser for simultaneous processing and measurement has been used. READ MORE
