  1. 1. Computational Modelling for Cavitation and Tip Vortex Flows

    Author : Abolfazl Asnaghi; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Cavitation; SST k − ω; OpenFOAM; Propeller; LES; Numerical simulation; Cur- vature correction; Elliptical foil; Inception; Twisted Delft foil;

    Abstract : Cavitation often brings negative effects, such as performance degradation, noise, vibration, and material damage, to marine propulsion systems, but for optimum performance, cavitation is almost inevitable. Therefore, it is necessary to better understand cavitation in order to maximize the performance without encounter- ing severe problems. READ MORE

  4. 4. The shear plate dowel joint : Research on a novel connection for heavy timber structures

    Author : Gustaf Larsson; Byggnadsmekanik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; timber connection; rubber foil; resilient bond line; single dowel; heavy timber structures;

    Abstract : An increased use of wood can reduce the environmental footprint of the building sector. In order to improve the competitiveness of heavy timber structures, the thesis presents a novel type of timber connection with a high degree of prefabrication. READ MORE

  5. 5. Mechanics and Failure in Thin Material Layers : Towards Realistic Package Opening Simulations

    Author : Eskil Andreasson; Sharon Kao-Walter; Gabriella Bolzon; Blekinge Tekniska Högskola; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; aluminium foil; FEM; LDPE; localisation; necking; polymer; progressive damage; semi-crystalline; simulation; virtual twin;

    Abstract : The final goal of this PhD-work is an efficient and user-friendly finite element modelling strategy targeting an industrial available package opening application.  In order to reach this goal, different experimental mechanical and fracture mechanical tests were continuously refined to characterize the studied materials.
