  2. 1. The mechanics in two nanosized systems : Size effect and threshold field

    Author : Martin Olsen; Håkan Olin; Ulf Lindefelt; Sven Öberg; Mittuniversitetet; []
    Keywords : ;

    Abstract : This thesis investigates the mechanics in two nanosized system. Paper I investigates a size effect in a cantilever nanowire affecting its resonance frequency. Paper II reveals a threshold field for the formation of a mound by the diffusion of surface atoms on a substrate under a STM-tip. READ MORE

  5. 3. 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

  6. 4. Adhesive Joints in Timber Engineering. Modelling and Testing of Fracture Properties

    Author : Erik Serrano; Byggnadsmekanik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood; test method; tensile strength; stress distribution; size effect; numerical simulation; laminating effect; laminated beams; joint; glued-laminated timber; glued-in rod; fracture mechanics; finite element method; finger-joint; experiment; damage; constitutive modelling; adhesive; bending strength; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp; Construction technology; Anläggningsteknik; Material technology; Materiallära; materialteknik;

    Abstract : This thesis, which is a compilation of seven papers, concerns the mechanical testing, numerical analysis and constitutive modelling of wood-adhesive bonds in timber engineering. Applications such as finger-joints, glued-laminated timber and glued-in rods are considered. READ MORE

  7. 5. Essays on Credit Risk

    Author : Caren Guo Nielsen; Nationalekonomiska institutionen; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Asset pricing; equity returns; size effect; value effect; momentum effect; credit risk effect; credit default swap; banks; asset risk; credit risk; portfolio choice; risk-based capital regulation; bank bailouts; moral hazard; distress risk; capital injections; TARP; CPP; market discipline; financial crisis;

    Abstract : This dissertation covers the issues related to credit risk that stem from the recent financial crisis and that are concerned by investors, financial intermediaries, and governments. The results of the research have important implications for asset managers, such as using the information from the credit risk market to rebalance stock portfolios, and for policy makers in regulating or bailing out banks.
