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

    Author : Ebrahim Harati; Lars-Erik Svensson; Leif Karlsson; Högskolan Väst; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 22. Rock Mechanical Effects of Cement Grouting in Hard Rock

    Author : Staffan Swedenborg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : A pre-grouted rock mass is subjected to stress re-distribution as the tunnel excavation progresses. The strength and deformation characteristics of grouted rock joints are therefore of interest in any effort to predict the rock mechanical behavior as well as the failure of sealing in a grouted rock mass.
