  4. 8. Constitutive Behaviour and Fracture of Adhesive Layers : Inverse Methods and Energetic Balance

    Författare :Svante Alfredsson; Högskolan i Skövde; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adhesive layer; constitutive behaviour; fracture; energy release rate; shear fracture; mode-mixity; experimental method; inverse solution; multi-material joints; TECHNOLOGY; TEKNIKVETENSKAP; Teknik; Technology;

    Sammanfattning : In the automobile industry, current demands on reduced emissions with maintained or even increased crash worthiness, forces the industry to seek weight-reducing designs. The possibility to use lightweight materials is obviously attractive. At joints, these lightweight materials have to be connected to high-strength or low-cost materials. LÄS MER

  5. 9. Meso-Mechanical Modeling of Thin Adhesive Layers

    Författare :Kent Salomonsson; Högskolan i Skövde; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adhesive layer; meso-mechanical; FEM; RVE; SEM; Engineering mechanics; Teknisk mekanik; Technology; Teknik;

    Sammanfattning : A thin adhesive layer is analyzed using a representative volume element (RVE). The RVE is comprised by, both continuum and interfacial finite elements. The interface elements allow for crack initiation and crack propagation. To obtain realistic results from the RVE simulation, an in situ scanning electron microscopy (SEM) study is performed.

  7. 10. Interfacial Properties of Film Forming Proteins and their Layer-by-Layer Assembly with Nanoparticles

    Författare :Olga Krivosheeva; Per Claesson; Thomas Arnebrant; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein adsorption; mussel adhesive protein; Mefp-1; hydrophobins; HFBI; HFBII; adsorption kinetics; layer-by-layer; stability; cross-linking; zeta-potential; dual polarization interferometry; quartz crystal microbalances;

    Sammanfattning :  The aim of this thesis work was to investigate the interfacial properties of film forming proteins, stability of the layers created by them, and their interactions with nanoparticles. Mussel adhesive protein (Mefp-1) and hydrophobins (HFBI and HFBII) were the three main proteins used. LÄS MER
