  2. 1. Caving mechanisms for a non-daylighting orebody

    Author : Sraj Umar Banda; Jonny Sjöberg; Björn Nilsen; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sublevel caving; numerical analysis; laser scanning; seismic data; large-scale structure; rock mass characterization; failure mechanism; discontinuum modeling; continuum modeling; caving analysis; voronoi modeling; bonded block model; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Abstract : The sublevel caving mining method is a mass production method with potentially very low operational costs. The success of this method is dependent on, among other factors, the cavability of the orebody and the overlying rock mass. READ MORE

  4. 2. Modeling of rigid foams

    Author : Joonas Köll; Dan Zenkert; Lorna Gibson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The morphology and elastic properties of foams are investigated using models accounting for the cellular structure. Different modeling approaches are evaluated and compared to the cellular structures of real foams. The aim is to find an approach that produces realistic models that can be adjusted to match morphology measures taken form real foams. READ MORE

  5. 3. Micromechanical modeling of two-phase steels by voronoi cells

  6. 4. Microstructural finite element modeling of metals

    Author : Mikael Nygårds; KTH; []
    Keywords : ;

    Abstract : The mechanical properties of metals have been investigated.This has been done by creating micromechanical models based onthe microstructural data available for the materials ofinterest. Thus, models containing a grain structure withappropriate constitutive equations have been created. READ MORE

  7. 5. Modeling drying of iron ore pellets

    Author : Anna-Lena Ljung; Graham Nathan; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : Iron ore pellets are a highly refined product supplied to the steel making industry for use in blast furnaces or direct reduction processes. The use of pellets offers many advantages such as customer adopted products, transportability and mechanical strength yet the production is time and energy consuming. READ MORE
