  1. 1. Wood and moisture-induced strains in a large deformation setting in 3D

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Fredrik Ström; Anwar Obeido; [2022]
    Keywords : Total Lagrangian; Finite element method; Large deformation theory; Deformation gradient decomposition; Moisture-induced strains; Hygroscopic; Orthotropic.;

    Abstract : Many studies have previously been done on moisture-induced strains in wood. An in- finitesimal/engineering strain model has been used for most of these studies, which is often an accurate approximation for small rotations. However, if large deformations oc- cur, then fictive strains are obtained resulting from the simplified engineering strain. READ MORE

  3. 2. The influence of passive measures on the highly demanding room climate requirements of a museum building in terms of sustainability

    University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Author : Jasmin Jost; [2021]
    Keywords : museum; museum climate; conservation requirements; climate risk assessment; indoor environment; thermal comfort; thermal mass; moisture buffering; hygroscopic materials; life cycle assessment LCA ; Technology and Engineering;

    Abstract : In the exhibition space of a museum, a compromise between the requirements for the preservation of cultural goods and thermal comfort criteria for visitors has to be applied. Such a high level of control without allowing fluctuations in temperature and relative humidity poses a big challenge to the air conditioning systems to maintain these very specific hygrothermal conditions.

  4. 3. Optimizing the sealing of tubular heating elements

    University essay from Lunds universitet/Materialteknik

    Author : Victor Almblad; [2019]
    Keywords : Technology and Engineering;

    Abstract : Tubular heating elements, produced by Backer AB are today commonly used, serving as systems for intelligent heating in automotive, medical and household industries. Tubular heating element consists of a mantle, resistance wire, electrical insulation (magnesium oxide) and a sealing. READ MORE

  5. 4. Investigating the performance of hempcrete as an option for retrofitting masonry buildings

    University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö; Lunds universitet/Avdelningen för Energi och byggnadsdesign

    Author : Henry Lanham; [2019]
    Keywords : Hempcrete; lime-hemp Miljöbyggnad; moisture safety; future climate; energy use; mould risk.; Technology and Engineering;

    Abstract : One fifth of the energy consumed by buildings in Sweden is by those built before 1945, many of them constructed from solid masonry walls. Improving their heating energy consumption is a challenge we must face in light of human’s impact on climate change as well as increasing energy costs. READ MORE

  6. 5. Effect of relative humidity and temperature on the strength properties of finger-jointed furniture components from solid scots pine

    University essay from Linnéuniversitetet/Institutionen för skog och träteknik (SOT)

    Author : Gustaf Lindstam; [2018]
    Keywords : Finger-joint;

    Abstract : Mechanical strength in wood has always been compromised due to the complex behaviours of the material when interfered with moisture and heat. These factors has always limited the use of the material. READ MORE
