  1. 1. Numerical modelling of geomaterials at failure

    University dissertation from Department of Construction Sciences, Lund University

    Author : Alex Spetz; Lund University.; Lunds universitet.; [2019-09-19]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; soil-structure interaction; soil plasticity; phase-field fracture model; compression driven fractures; artificial rock; porous rock; finite element analysis; isogeometric analysis; NURBS; numerical methods;

    Abstract : Geotechnical engineering is the science dealing with mechanics of soils and rocks and its engineering applications. Geotechnical engineering projects vary in a wide range, from evaluation of the stability of natural slopes and man-made soil deposits, to the design of earthworks and foundations. READ MORE

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; exponential decay; modelling; fractured rock; classical mechanics; quantum mechanics; Mathematical and general theoretical physics; relativity; statistical physics; thermodynamics; Matematisk och allmän teoretisk fysik; klassisk mekanik; relativitet; kvantmekanik; gravitation; statistisk fysik; termodynamik; Environmental technology; pollution control; kontroll av utsläpp; Miljöteknik; conformal flow; heat as a tracer; KBS-3; stress field; temperature field; analytical solution; salt buoyancy; groundwater flow; nuclear waste repository; aquifer thermal energy storage; Fysicumarkivet A:1998:Probert;

    Abstract : The underground is a vast region, which is, too a large extent, unused by man. It has a large potential as a storage facility due to its vastness and availability. This thesis, which consists of eleven papers and reports, deals with nuclear waste repositories in solid rock and with aquifer thermal energy storage systems. READ MORE

  3. 3. Analysis and Modelling of Mineral and Element Composition in Compression Breakage

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Lorena Guldris Leon; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; minerals; rare metals; elements; cone crusher; modelling; compressive crushing;

    Abstract : The outstanding properties of tungsten and tantalum make them valuable metals and, in some cases, irreplaceable in applications. The growing interest due to the high economic importance and the limited supply places these metals in the critical metals risk list. READ MORE

  4. 4. Novel methods for 3-D semi-automatic mapping of fracture geometry at exposed rock faces

    University dissertation from Institutionen för anläggning och miljö

    Author : Quanhong Feng; KTH.; [2001]
    Keywords : 3-D laser scanner; close-range photogrammetry; engineering geology; fracture geometry; fracture mapping; rock engineering; rock faces; rock mechanics; three-dimension; total station;

    Abstract : To analyse the influence of fractures on hydraulic andmechanical behaviour of fractured rock masses, it is essentialto characterise fracture geometry at exposed rock faces. Thisthesis describes three semi-automatic methods for measuring andquantifying geometrical parameters of fractures, and aims tooffer a novel approach to the traditional mapping methods. READ MORE

  5. 5. Numerical prediction of wear in industrial raw material flow

    University dissertation from Institutionen för anläggning och miljö

    Author : Dan Forsström; Luleå tekniska universitet.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : Abrasive wear is largely involved in many industrial processes, and has far reaching economic consequences which involve not only the costs of replacement, but also the costs involved in machine downtime and lost production. Constructions and machines like conveyers, chutes and dumper truck bodies are often exposed to abrasive wear during handling of industrial raw granular material flow e. READ MORE
