  1. 1. Validation of Finite Element Model of a Tetra Pak Package

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Warsame Mohamed Ali; Abdullahi Abdi Hashi; [2023]
    Nyckelord :Abaqus; HDPE; Package testing; Validation; Abaqus; HDPE; Pakettestning; Validering;

    Sammanfattning : There is a high dependency on accurate finite element models in the packaging industry for concept selection, design and virtual validation of packages. One of themost used materials for these packages is High-Density Polyethylene (HDPE). Thismaterial is highly anisotropic, strain rate dependent and has different behavior intension and compression.

  3. 2. Plastic deformation of hot riveted joints acting in shear

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Victor Gard; [2023]
    Nyckelord :;

    Sammanfattning : A popular way to maintain old rivet connections is to reuse the old connection and replace the old rivets with high grade steel bolts. In doing so the behavior of the joint can change due to the new geometry, where a gap between the new bolt and the rivet hole emerges. LÄS MER

  4. 3. Development of Elastic Mechanism for actuation of Valve

    Master-uppsats, KTH/Maskinkonstruktion

    Författare :Nidhi Menon; [2023]
    Nyckelord :Compliant mechanism; Engine; HGR valve; Heat gas recirculation; Eftergivlig mekanism; HGR-ventil; läckage; varmgasåtercirkulationsventilen;

    Sammanfattning : The HGR valve, or hot gas recirculation valve, is an essential component of modern internal combustion engines. Its main function is to reduce emissions of nitrous oxide (NOx), which is a harmful pollutant produced during combustion. LÄS MER

  5. 4. Characterization of Kelvin Cell Cored Sandwich Structures with Analysis and Experiments

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Sabahattin Bora Günay; [2023]
    Nyckelord :Kelvin Cell; Sandwich Structure; Space Structures; Three Point Bending Test; Structural Stiffness; Kelvin-cell; smörgåsstruktur; rymdstrukturer; trepunktsböjningstest; strukturell styvhet;

    Sammanfattning : In order to satisfy the mechanical requirements for space structures, achieving lightweight designs is of the greatest significance. The primary focus of this study is the utilization of Kelvin cell core in the design of sandwich structures for space applications. LÄS MER

  7. 5. Exact Solutions in Planar Elasticity via the Cauchy-Riemann Equations

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Andreas Granath; [2022]
    Nyckelord :;

    Sammanfattning : In many engineering applications, one is interested in structures with elastic properties which undergo deformation due to external loads. This interest has motivated a deep study of the equations underlying the deformation and how to solve them during the two last centuries. LÄS MER
