  1. 16. Flow Paths in the Húsmúli Reinjection Zone, Iceland

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Sigrún Tómasdóttir; [2018]
    Keywords : Húsmúli; Hellisheiði Power Plant; geothermal reinjection; tracer tests; numerical modeling; Húsmúli; Hellisheiði kraftverk; geotermisk injektion; spårtest; numerisk modellering;

    Abstract : Reinjection of spent geothermal fluids has become common practise in geothermal power plants. Reinjection can, despite being mostly beneficial, have unwanted effects such as cooling of nearby production wells and injection-induced earthquakes. READ MORE

  3. 17. Mechanical properties of bulk alloys and cemented carbides

    University essay from KTH/Materialvetenskap

    Author : Alexander Engman; [2018]
    Keywords : ICME; Cemented carbides; Cobalt;

    Abstract : The usage of cobalt (Co) as binder phase material in cemented carbides has been questioned becauseof the potential health hazards associated with cobalt particle inhalation. Cobalt is used because ofits excellent adhesive and wetting properties, combined with adequate mechanical properties. READ MORE

  4. 18. An Attempt Towards FE-Modelling of Fracture Propagation in Railway Wheels

    University essay from KTH/Spårfordon

    Author : Fred Öhnander; [2018]
    Keywords : Railway wheel; Wheel-rail contact; Wear; Fracture initiation; Physical fracture propagation model; FE-model; Fracture mechanics; XFEM; Inclusion; Järnvägshjul; Hjul-räl-kontakt; Slitage; Sprickinitiering; Fysisk sprickbildningsmodell; FE-modell; Frakturmekanik; XFEM; Imperfektion;

    Abstract : The demand for higher velocities and heavier axle loads for freight trains leads to higher forces on the railway wheels which in turn lead to an increase in stresses on and below the surface of the wheel-rail contact. By time, this induces wear on the wheels which consequently lead to higher maintenance costs and in some cases accidents. READ MORE

  5. 19. Fracture prediction of stretched shear cut edges in sheets made of Dual-Phase steel

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Johannes Falk; [2017]
    Keywords : Strain; DP steel; Dual-phase steel; Autoform; Aramis; Fracture strain; Advanced High Strength Steels; AHSS; Fracture prediction;

    Abstract : Dual-Phase (DP) steels, part of the group of Advanced High Strength Steels (AHSS), are used by car manufactures due to its large strength to weight ratio. The high strength of the DP steel does have a negative impact on the formability during sheet metal forming and stretch forming, e.g. READ MORE

  6. 20. Comparison of Photogrammetry Interpretation with Physical Structural Field Measurements

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Fredrik Osterman; [2017]
    Keywords : Fracture mapping; photogrammetry; 3D-modelling; rock classification; field safety; Sprickkartering; fotogrammetri; 3D-modellering; bergklassificering; säkerhet i fält;

    Abstract : Fracture mapping of bedrock and knowledge about how fractures influence rock strength and stability is of great importance in a constructional context. These factors largely dictate where one can build and not build in rock, and to what extent reinforcements and safety measurements are needed. READ MORE
