  2. 1. Internal Stresses in Wood Caused by Climate Variations

    Author : Staffan Svensson; Avdelningen för Konstruktionsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction technology; climate variations.; sawn timber; kiln drying; mechano-sorption; hygro-mechanical; Wood; material testing; Anläggningsteknik;

    Abstract : This thesis is the result of a series of investigations on the hygro-mechanical behaviour of clear wood in the radial and tangential directions. Approximately half of the effort put into the investigations was concentrated on laboratory tests while the remaining effort was concentrated on modelling the observations made in the tests.

    Abstract : Wood has been used as a construction material for a very long time. The development of efficient industrial production processes of wood has expanded the use of the material with the introduction of new products, such as engineered wood products. READ MORE

  5. 3. Hygro-Mechanics of Wood Fibre Composite Materials

    Author : Kristian Stålne; Byggnadsmekanik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; homogenisation; Wood composite materials; modelling; stiffness; hygroexpansion; creep; mechanosorption;

    Abstract : The work presented in this thesis deals with modelling and testing of hygro-mechanical properties of wood fibre composite materials. The material studied experimentally is high pressure laminate, HPL, which is a wood fibre network composite, made up of craft paper impregnated with phenolic or melamine resin. READ MORE
