  1. 1. Method Development & Analysis of Seals using FEM

    University essay from KTH/Maskinkonstruktion

    Author : Lovisa Svanborg Östlin; [2023]
    Keywords : FEM; guidelines; hyperelastic materials; hyperelastic material models; method development; seals; FEM; riktlinjer; hyperelastiska material; hyperelastiska materialmodeller; metodutveckling; tätningar;

    Abstract : Hyperelasticity is a significant property of rubber, taken advantage of in engineering applications. A common application is the use of seals to prevent fluid transfer (liquid or gas) between solid regions. Volvo CE is often depending on external supplier when developing seals. READ MORE

  3. 2. Jet fragmentation in shaped charges

    University essay from KTH/Matematik (Avd.)

    Author : Joakim Ericson; [2022]
    Keywords : Shaped charges; numerical simulation; jet fragmentation; Riktad sprängverkan; numerisk simulering; strål-fragmentering;

    Abstract : This master thesis treats the numerical simulation of shaped charge jets and its fragmentation process. Shaped charges is a method to concentrate the effect of an explosive charge and penetrate deeply into a target due to a the formation of a jet with great penetration capabilities. READ MORE

  4. 3. Reinforcement and Bonded Block Modelling

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

    Author : Georgios Aristeidis Skarvelas; [2021]
    Keywords : Bonded Block Modelling; 3DEC; Tunneling; Reinforcement; Distinct Element Method; Numerical Modelling;

    Abstract : The objective of this master’s thesis is to evaluate the use of Bonded Block Modelling (BBM) in 3DEC software combined with hybrid rock bolts, for three different cases. These cases included the laboratory rock bolt case, the shearing case and the blocky rock mass case. READ MORE

  5. 4. Internal Erosion and Dam Stability : Analysis of the internal erosion effects on stability of an embankment dam

    University essay from Luleå tekniska universitet/Geoteknologi

    Author : Arthur Jedenius; [2018]
    Keywords : Internal erosion stability finite element analysis method plaxis slope seep;

    Abstract : Embankment dams encounter several problems in terms of dam safety. One of those problems is called internal erosion. This phenomenon is induced by the movement of fine particles within the dam due to seepage forces. If the dam is not able to self-heal, the eroded zones will increase which will eventually cause the dam to fail. READ MORE

  6. 5. Experimental Investigation of Hydrodynamic Effects on a Vibrating Kaplan Runner

    University essay from Luleå tekniska universitet/Strömningslära och experimentell mekanik

    Author : Jakob Hedlund; [2017]
    Keywords : FSI; fluid-solid interactions; Kaplan runner; hydrodynamic; added mass; added damping; vibrations;

    Abstract : An experimental investigation of a vibrating Kaplan turbine runner was performed in order to understand the hydrodynamic effects and to obtain or confirm the mass and damping coefficients used for dimensioning at the design stage. Improved design can lead to increased efficiency and lifetime of hydropower stations. READ MORE
