  1. 1. Ultimate and Residual Strength Assessment of Ship Structures

    Författare :Artjoms Kuznecovs; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ship structures; collision; corrosion; residual strength; ultimate strength; age-related degradation; nonlinear FEA; Smith method;

    Sammanfattning : The prevention of ship structural failures and reduction of accident consequences contribute to increased safety at sea and reduced environmental impact. A need for reliable and efficient ship designs facilitates knowledge accumulation and the development of tools for the assessment of hull structural responses to acting loads. LÄS MER

  2. 2. High strength steel : local buckling and residual stresses

    Författare :Mattias Clarin; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Sammanfattning : High strength steel provide designers with the possibility of creating more slender and weight efficient structures than would be possible if using steels with lower strength. To be able to do this, a structural designer needs updated and validated codes as aid in their work. LÄS MER

  3. 3. Fatigue strength of welds in 800 MPa yield strength steels : Effects of weld toe geometry and residual stress

    Författare :Ebrahim Harati; Lars-Erik Svensson; Leif Karlsson; Högskolan Väst; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fatigue strength; Residual stress; Welds; Weld toe geometry; High strength steel; Weld Impression Analysis; Laser Scanning Profiling; Structured Light Projection; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : Nowadays there is a strong demand for lighter vehicles in order to increase the pay load. Through this the specific fuel consumption is decreased, the amount of greenhouse gases is lowered and the transport economy improved. One possibility to optimize the weight is to make the components from high strength steels and join them by welding. LÄS MER

  4. 4. Adhesion strength of HVOF sprayed Inconel 718 coatings

    Författare :Christophe Lyphout; Chalmers University of Technology; []
    Nyckelord :Adhesion Strength; Residual Stress; Inconel 718; Thermal spray; Finite Element Method; HVOF; High Velocity Oxy-Fuel;

    Sammanfattning : Thermal spray technology in general is nowadays recognized as an industrial process, mature enough to apply coatings on different substrate materials that protect parts against wear, corrosion, heat, or combinations of these. The quality demands on coating homogeneity and adhesion strength are, nowhere more than in the automotive and aeronautic industries, continuously increasing. LÄS MER
