  1. 1. Multiscale & Multiphysics Modelling of Thrust Pad (Air) Bearings

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Nipon Roy; [2023]
    Keywords : Finite element modelling; Air bearing; Multiphysics simulations; Air lubrication; surface texture; Topology optimization;

    Abstract : Without lubrication, machines are not imaginable to perform over a long period of time and complete their designated operations. With its omnipresent availability, the air is capable of functioning as a lubricant in long operations very efficiently. Moreover, thrust bearings support axial loads and transmit power at the same time under heavy loads. READ MORE

  3. 2. Evaluation of a computational method for natural fiber-reinforced plastics

    University essay from KTH/Hållfasthetslära

    Author : Anna Lim; [2023]
    Keywords : PPNF; Composite material; fiber orientation; natural fiber; coupled analysis; PPNF; Kompositmaterial; fiberorientering; naturfiber; kopplad analys;

    Abstract : The importance of using natural fiber composites (NFCs) has been addressed as a substitution for synthetic fibers, such as glass and carbon fibers. This substitution contributes significantly to reducing greenhouse gas emissions, aligning with the environmental responsibilities of engineering industries. READ MORE

  4. 3. Structural responses due to underwater detonations : Validation of explosion modelling methods using LS-DYNA

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Gustav Blomgren; Ebba Carlsson; [2023]
    Keywords : Underwater explosion; UNDEX; detonation; fluid structure interaction; FSI; SSA; S-ALE; shock-wave; explosive; PETN; explosive modelling; Sub-Sea Analysis; Structured ALE; Arbitrary Lagrangian Euler; Multi Material Arbitrary Lagrangian Euler; MMALE; LS-DYNA;

    Abstract : Modelling the full event of an underwater explosion (UNDEX) is complex and requires advanced modelling methods in order to achieve accurate responses. The process of an UNDEX includes a series of events that has to be considered. READ MORE

  5. 4. Jet Grout Bottom Plug in Deep Excavations : Numerical Analysis of a Tunnel Project

    University essay from KTH/Jord- och bergmekanik

    Author : Ida Schjelderup; [2022]
    Keywords : Jet grouting; jet grout bottom plug; cut-and-cover tunnel; tunnel design;

    Abstract : This master thesis has investigated the performance of a deep excavation with a jet grout bottom plug used to prevent bottom heave and hydraulic uplift failure. The concept of a jet grout plug as a structural and sealing component in a specific case was studied, namely one of the tunnel sections of The West Link tunnel project in Gothenburg. READ MORE

  6. 5. Characterization of commercially pure titanium under supercritical conditions : By means of hybrid numerical-experimental approach

    University essay from KTH/Materialvetenskap

    Author : Ricardo Rodríguez; [2022]
    Keywords : ;

    Abstract : Material characterization was addressed by solving the inverse engineering problem to mechanical properties by means of finite element analysis and computational optimization. High-temperature and high strain-rate data from split Hopkinson pressure bar tests on commercially pure titanium were used in the study. READ MORE
