  2. 6. Strengthening steel beams with adhesively bonded composite laminates

    Author : Dag Linghoff; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFRP laminate; adhesive bond; interfacial stresses.; Strengthening;

    Abstract : Strengthening steel structures with carbon-fibre-reinforced-polymer (CFRP) laminates bonded to the steel substrate has become an interesting alternative to the conventional strengthening methods. The current research comprises analyses of the global and local behaviour of double-symmetrical steel beams strengthened with CFRP laminate bonded with adhesive to the tension flange. READ MORE

  4. 7. Diluent and Solvent Effects in Liquid-Liquid Extraction Systems based on bis-triazine-bipyrididine (BTBP)-class Ligands

    Author : Elin Löfström Engdahl; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Used nuclear fuel; Density; Solvent; Extraction vs. time; BTBP; GANEX; Liquid-Liquid Extraction; Interfacial tension; Diluent;

    Abstract : Used nuclear fuel taken directly from a reactor is radiotoxic for mankind and its environment for a long time. One of the major contributions to the long time radiotoxicity is the presence of a group of elements called the actinides. READ MORE

  5. 8. First-Principles Investigation of Bulk and Interfacial Properties of Cu-Co Binary System

    Author : Changle Li; Levente Vitos; Hongbin Zhang; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : Due to the complex nature of phase interfaces, acquiring precise interfacial energies is usually a big challenge for both experimental measurements and computational modelings. In this thesis, we put forward an efficient route for assessing the temperature dependence of the interfacial energy using density functional theory (DFT). READ MORE

  6. 9. Durability of Embedded Fibre Optic Sensors in Composites

    Author : Klas Levin; KTH; []
    Keywords : composites; fibre optic sensor; embedded EFPI sensor; bragg grating sensor; durability. Fatique; impact strain measurement;

    Abstract : This thesis concerns various aspects of the durability offibre optic sensors embedded in composite. Since repair orreplacement of embedded sensors is not generally possible, thefunctional reliability of embedded sensors is one of the mostimportant prerequisites for successful use. READ MORE

  7. 10. Low Cycle Fatigue Reliability and Interfacial Reaction of Lead-free Solder Joints for Electronic Packaging

    Author : Sun Peng; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite Element Simulation; Reliability; Intermetallic Compounds; Lead-free Solder; Low Cycle Fatigue;

    Abstract : Two key technologies in electronics industry are chip technology and packaging technology. Solder plays a crucial role in the assembly and interconnection in the electronic packaging industry. As a joint material, solder provides electronic, thermal and mechanical continuity. READ MORE
