  1. 16. A SIMULATION WITH FINITE ELEMENTS TO MODEL STEEL SHEET SLITTING : A Master Thesis in Engineering Physics

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Adam Ahlgren Peters; [2019]
    Keywords : Finite element Method; steel; steel shearing; high performance steels; Finita Element Metoden; FEM; stål; stålklippning; höghållfasta stål; industriell ståltillverkning; spaltning;

    Abstract : A steel slitting process is simulated using FEM (Finite Element Method) in order to see potential defects along the edge in a steel sheet after it has been cut. The model's results were compared to microscope images of the steel sheet in order to verify accuracy. READ MORE

  3. 17. Evaluation of influence from matedness on the peak shear strength of natural rock joints

    University essay from KTH/Byggvetenskap

    Author : Emil Andersson; [2019]
    Keywords : Rock joints; Peak shear strength; Matedness; Casagrande et al. criterion; Peak friction angle; Shear strength; Bergssprickor; Maximal skjuvhållfasthet; Passning; Casagrande et al. kriterium; Friktionsvinkel; Skjuvhållfasthet;

    Abstract : In Sweden, the rock mass is commonly used for construction of tunnels and caverns. The rockmass is also used as a foundation for large structures such as bridge abutments and dams. Forthese structures, the understanding of the rock mechanical properties play a key role for reachingan acceptable safety level and minimizing cost. READ MORE

  4. 18. Numerical Methods for Simulating the Metal Shearing Process : A Novel Numerical Model for the Punching of Metals

    University essay from Luleå tekniska universitet/Material- och solidmekanik

    Author : Andreas Svanberg; [2019]
    Keywords : Punching; Blanking; Smoothed Particle Galerkin; SPG; LS-DYNA; FEM; Metal shearing; cutting; particle method; thesis; Stansning; klippning;

    Abstract : When dealing with the separation of materials, the metal shearing process such as punching, is widely used in theindustry due to its time efficient manner. There is however, a need to better understand the process in order toimprove quality of the final product. READ MORE

  5. 19. Relationship between Shear-Wave Velocity and Consolidation Parameters of Peat

    University essay from Lunds universitet/Geoteknik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Oskar Markström; [2018]
    Keywords : shear wave velocity; peat; constant rate of strain; consolidation parameters; von Post; Technology and Engineering;

    Abstract : There is a need of developing methods for evaluating material parameters for peat. It is hard and costly to obtain undisturbed samples for laboratory testing of the peat. Therefore, in this thesis the possibility of using in situ measurements of the shear wave velocity for first order estimates of the consolidation parameters has been investigated. READ MORE

  6. 20. Evaluation of roof-pillar interface and its effect on pillar stability in mine #101

    University essay from Luleå tekniska universitet/Geoteknologi

    Author : Viktor Lönnies; [2017]
    Keywords : Roof-pillar interface; rock mechanics; coal; numerical modelling; FLAC;

    Abstract : The company Rio Deserto is currently mining the famous Barro Branco coal seam in the state of Santa Catarina located in the south of Brazil. One of their coal mines, #101, is experiencing problems related to the pillars in one panel. READ MORE
