  1. 1. Deriving Geothermal Reservoir Properties from Tomographic Models

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Samantha Kim; [2019]
    Keywords : Geothermal reservoir; super-critical fluids; optimization; seismic tomography; effective medium model; Iceland; Geotermisk energi; seismisk; mediummodel; reservoir; spricktäthet; superkritisk vätska optimisering;

    Abstract : The effectiveness of the heat transfer in a geothermal reservoir strongly depends on its temperature, pressure and rock type. A porous and fractured rock is essential to provide a hot fluid circulation to a geothermal power plant. READ MORE

  3. 2. Failure Modeling of Curved Composite Beams : Numerical Modeling of Failure Onset and Propagation in L-Profile Beams

    University essay from KTH/Lättkonstruktioner

    Author : Suhas Gururaj Shetty; [2018]
    Keywords : ;

    Abstract : The high strength/stiffness-to-weight ratio that composite materials exhibit has led to the utilization of composites as alternative to traditional materials in weight-critical applications. However, the highly anisotropic nature of composites renders the strength prediction under complex loading challenging. READ MORE

  4. 3. Avoiding Fracture Failure of a Crusher Disk in a Lamp Re-cycling Machine

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Mahesh Meesala; Swapna Armoor; [2012]
    Keywords : Crushers; Fracture; Re-design; FEM; Simulation; ABAQUS and INVENTOR;

    Abstract : The crusher disk in lamp recovery device used for crushing aluminum end caps is breaking while crushing for unknown reasons. Therefore it is important for design engineers to be able to find out the possibilities of fracture failure and also provide prevention methods for it during design proposals. READ MORE

  5. 4. Fracture Mechanical Trouser Taer Testing of thin polymer films

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Nasir Mehmood; Tan Mao; Gaurav Bhupati; [2012]
    Keywords : Key Words: PP; Mode I ; Mode III; Tensile test; ABAQUS simulation; Crack shapes; Tearing behavior; EWF; Polarized light; SEM microscope.;

    Abstract : Tensile and Trouser tear tests of thin packaging polymer films have been done successfully in this research thesis. Two different polymers (PP and LDPE) are used. Mode I and Mode III fracture tests have been used for crack propagation analysis. Several experiments are performed to calculate the material parameters. READ MORE

  6. 5. Study of Two Models for Tearing Resistance Assessment Using Essential Work of Fracture Method

    University essay from Blekinge Tekniska Högskola/Avdelningen för maskinteknik

    Author : Min Hu; [2008]
    Keywords : Essential Work of Fracture EWF ; Two-leg Trousers Tear test; Out-of-plane Fracture;

    Abstract : The thesis takes an insight look into two different models(two-zone and three-zone models)for describe the deformation and fracture behaviour of the tearing ligament.By earlier works,these two different models based on Essential Work of Fracture approach was proved to be capable for predicting the specific total work of fracture along the tear path across all plastic zones.
