  2. 1. Multiscale Modelling of Reinforced Concrete Structures

    Author : Adam Sciegaj; Chalmers tekniska högskola; []
    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; cracking; reinforced concrete; computational homogenisation; bond-slip; multiscale;

    Abstract : Concrete cracks at relatively low tensile stresses; cracks open up for ingress of harmful substances, negatively affecting the durability of reinforced concrete structures. Crack widths are thus limited in the design codes, and accurate predictions are needed, especially for large reinforced concrete structures such as bridges or nuclear reactor containment buildings.

  4. 2. Prestress in Nature and Technics

    Author : Alexander Sehlström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Geometrical stiffness; Prestress; Form finding; Architecture; Structural design; Stress pattern; Engineering; Conceptual design;

    Abstract : To direct the forces of nature is a central task in the creation of spaces and load-carrying structures for architecture. This research investigates how prestress can be used as a design tool for the creation of material efficient and well-functioning structures, and in early design stages contribute to sustainable, functional and beautiful architecture.

  5. 3. Towards Large-scale and Feasible Exploitation of Tunicate Cellulose and Cellulose Nanocrystals for Different Applications

    Author : Yadong Zhao; Jiebing Li; Mikael E. Lindström; Gunnar Westman; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Tunicates are a group of filter-feeding animals that live in the ocean. They are widely distributed throughout the world and are a major contributor to the fouling problem in aquaculture. READ MORE

  6. 4. Micromachined epitaxial colossal mognetoresistors for uncooled infrared bolometer

    Author : Joo-Hyung Kim; Alexander M. Grishin; Yael Nemirosky; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; La0.67 Sr; Ca 0.33MnO3 LSCMO ; La0.67Sr0.33MnO3 LSMO ; Electrophysics; Elektrofysik;

    Abstract : High quality perovskite manganites, La1-xAxMnO3 (A = Ca, Sr, Ba) are very attractive materials due to their great application potential for magnetic memory, uncooled infrared (IR) microbolometer and spintronics devices. This thesis presents studies of the growth and material characterization (including structural, electrical, magnetic and noise) of epitaxial manganite films on Si and GaAs. READ MORE
