    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Rafail-Nikolaos Dimitriou; [2020]
    Keywords : ;

    Abstract : In the mining industry, finite element analysis (FEA) and experimental tests are essential for the verification of mechanical properties and for performing parametric studies. Such practices require lots of resources and, sometimes, long computational time. READ MORE

  5. 4. Binder Migration in Double Pressed Drill Bit Inserts

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

    Author : Axel Bjerke; [2018]
    Keywords : Physics and Astronomy;

    Abstract : It is possible to produce functionally graded cemented carbides on a large scale by double pressing. Being able to predict the binder migration in WC-Co cemented carbides during the sintering is essential to the design of such cemented carbides. The cobalt content is one of the main factors determining the hardness gradient. READ MORE

  6. 5. Study of a new method to measure the stresses in rock by image technology : Use of sawn slots and DIgital Image Correlation

    University essay from Luleå tekniska universitet/Geoteknologi

    Author : Patrik Emanuelsson; [2018]
    Keywords : Digital Image Correlation; Numerical modelling; Stress measurement; Sawn slots;

    Abstract : In rock constructions and mining it is important to know the current stress situation in the rock due to safety and construction reasons. Two of the widely used stress measurement methods are overcoring and hydraulic fracturing. Both methods are expensive, need new boreholes, and are complex and time consuming. READ MORE
