  1. 1. Adapted data collection in field utilizing RMR and the Q-system

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Amanda Olsson; [2024]
    Keywords : Rock mass classification; Q-slope; SMR; Slope stability;

    Abstract : The focus on slope stability has increased rapidly in Norway over the last years due to several unwanted landslides. In Norway, the most used method today to classify the rock mass and to determine the required reinforcement, is the Q-system. In addition to that the RMR method is also a commonly used method.

  3. 2. Rock Wedge Stability Assessment : A Comparative Analysis of Limit Equilibrium and Discrete Element Methods

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Vilma Nordh; [2024]
    Keywords : Numerical modelling; wedge stability; 3DEC; UnWedge;

    Abstract : Rock wedge stability is a common concern in underground excavations. Since the wedge stability influences the support design, it is important to use a wedge stability analysis method that can capture factors like excavation geometry, joint parameters and properties, rock mass properties, rock cover, and stress field as accurately as possible.

  4. 3. Interaction for flexural column buckling : Analytical procedures compared with FE-simulations

    University essay from KTH/Bro- och stålbyggnad

    Author : Noah Norberg; [2023]
    Keywords : ;

    Abstract : This master's thesis presents a study on the stability of steel structures under flexural bucklingconstraints. The study focuses on the interaction and behaviour of flexural buckling formulas in SSEN-1993-1-1 and Swedish BSK and the performance of actual structural members subjected to suchconstraints.

  5. 4. Simulations of a self-stabilizing fully submerged hydrofoil

    University essay from KTH/Matematik (Avd.)

    Author : Henry Jacobson; [2023]
    Keywords : Hydrofoil; Self-Stabilizing; Lifting Line Theory; Fluid Mechanics; Numerical Methods; Backward Differentiation Formula; Fully Submerged Hydrofoil; Bärplan; bärplansbåt; självstabiliserande; lyftande linjeteori; strömningsme- kanik; numeriska metoder; Backward Differentiation Formula; fullt nedsänkt bärplan;

    Abstract : Two models of a self-stabilizing hydrofoil system is developed where the effects from the struts and hydrofoil give torques for angular rotations. Lifting line theory for the hydrofoil which can twist is used. Nonlinear versions of the models are also developed and compared to find that the linear models use valid approximations. READ MORE

  6. 5. Simulation of low frequency acoustic waves in small rooms : An SBP-SAT approach to solving the time dependent acoustic wave equation in three dimensions

    University essay from

    Author : Alva Fährlin; Olle Edgren Schüllerqvist; [2023]
    Keywords : room acoustics; numerical methods; SBP; SAT; acoustic wave equation.;

    Abstract : Low frequency acoustic room behaviour can be approximated using numerical methods. Traditionally, music studio control rooms are built with complex geometries, making their eigenmodes difficult to predict mathematically. READ MORE
