  1. 16. 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

  3. 17. Modelling of a Glued Bolt Joint in Finite Element

    University essay from KTH/Hållfasthetslära

    Author : Tove Boivie; [2023]
    Keywords : Solid Mechanics; finite element method; adhesive; bolt; hybrid joint; Hållfasthetslära; finita element metoden; lim; skurv; hybrid förband;

    Abstract : This report presents a master thesis project at KTH at the school of Engineering Science. The project is done in collaboration with ABB Robotics, a company who develops industrial robots. A robot consists of several parts and the last structural part is the wrist. READ MORE

  4. 18. A comparison between tomographic and generated open cell metal foam structures

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

    Author : Jonathan Ebbesson; [2023]
    Keywords : Technology and Engineering;

    Abstract : This master thesis project presents steps on the image processing and reconstruction of an aluminium open-cell metal foam from $\mu$CT tomographic data. In addition, it also considers the generation of architecture foams using Voronoi Tessellation in combination with sphere packing algorithms. READ MORE

  5. 19. The Influence of Roughness on Electrical Properties of Single Rock Fractures

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Yu Hou; [2023]
    Keywords : Single fracture; Roughness; Current; Electrical properties; Relative standard deviation; Numerical simulations; Enkelfraktur; Grovhet; Ström; Elektriska egenskaper; Relativ standardavvikelse; Numeriska simuleringar;

    Abstract : To investigate the relationship between the structural characteristics of rough single fracturesand the electrical properties of the rock. In this study, a series of physical models of roughand smooth single fractures were established using the finite element method and Ohm's lawto test the electrical conductivity. READ MORE

  6. 20. Streamlining 3D City Modeling for Urban Flow Simulations by Automatic Integration of Multisource Topography

    University essay from Umeå universitet/Institutionen för fysik

    Author : Klara Lindroth; [2023]
    Keywords : automatic 3D city models; surface reconstruction; geometry pre-processing; CFD; OSM height attributes;

    Abstract : In the workflow of computational fluid dynamics, geometry preparation is commonly the most time-consuming step. For a fast CFD simulation, automatic surface reconstruction to obtain 3D city models for a chosen area is essential. To address this need, a literature study was conducted to map available data suitable for 3D city models. READ MORE
