  1. 6. Finite element modelling of hydroelasticity in hull-water impacts

    Författare :Ivan Stenius; Dan Zenkert; Pennny Temarel; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluid-structure interaction; hydroelasticity; hull-water impact; high-speed craft; slamming; explicit finite element methods; Vehicle engineering; Farkostteknik;

    Sammanfattning : The work in this thesis focuses on the use of explicit finite element analysis (FEA) in the modelling of fluid-structure interaction of panel-water impacts. Paper A, considers modelling of a two-dimensional rigid wedge impacting a calm water surface. LÄS MER

  3. 7. Usability of Textile Reinforced Concrete: Structural Performance, Durability and Sustainability

    Författare :Natalie Williams Portal; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sustainability; life cycle assessment; experimental methods; finite element analysis; durability; Textile reinforced concrete;

    Sammanfattning : Textile reinforced concrete (TRC) is an innovative high performance composite material consisting of open multi-axial textiles embedded in a fine-grained concrete matrix. Despite the fact that TRC-based research has revealed many promising attributes, it has yet to reach its recognition due to a lack of available design tools, standards and long-term behaviour.

  4. 8. RoPax Ship Collision – a Methodology for Survivability Analysis

    Författare :Per Hogström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; non-linear FEA; failure modelling; uncertainty analysis; Crashworthiness; sheet metal failure; ship collision; damage stability;

    Sammanfattning : Throughout the world, ships are continuously being declared as total losses and 10 to 15% of these accidents are collisions between ships. The consequences of a collision are diverse and depend on the ship type, e.g. oil outflow in the case of damaged tankers or loss of stability in damaged passenger ships. LÄS MER

  5. 9. Fibres in reinforced concrete structures - analysis, experiments and design

    Författare :Anette M Jansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; crack width; stress crack-width relationship; design methods; post cracking; analysis method; Fibre-reinforced concrete;

    Sammanfattning : Potential benefits from fibres in concrete are improved crack control and the possibility of more slender structures. The extent of the crack control depends, among other factors, on the amount of fibres added, and plays a great role for durability. LÄS MER

  7. 10. Process Modeling of Composite Manufacturing

    Författare :Mohammad Sadegh Rouhi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite element Analysis FEA ; Poro-Mechanics; Polymer Composites.; Manufacturing Technologies;

    Sammanfattning : The focus of this research thesis is toward developing a framework for holistic modeling of composites manufacturing of fiber reinforced structural composites. The processes that have been considered are Liquid Composite Molding (LCM) and Out Of Autoclave (OOA) processes, ranging from Liquid Resin Infusion (LRI) and Resin Transfer Molding (RTM) in LCM processes, to Vacuum Bag Only (VBO) and Evac prepregs in OOA processes.
