  1. 1. Correlation-based analysis on thin walled tubes

    Master-uppsats, Jönköping University/JTH, Produktionsutveckling

    Författare :Andreas Hedlund; Daniel Blom; [2022]
    Nyckelord :Thin-walled tubes; Crashworthiness; Energy absorption; Finite element method; Finite element method automation.;

    Sammanfattning : In the transportation sector, crash structures are often used to protect their inhabitants inthe event of a collision. These crash structures frequently utilize thin-walled tubes as energyabsorbers. The process of developing thin-walled tubes is iterative based and requires mul-tiple simulations, making it resource intensive. LÄS MER

  4. 3. Finite element modeling of straightening of thin-walled seamless tubes of austenitic stainless steel

    Kandidat-uppsats, Högskolan Dalarna/Materialteknik

    Författare :Robert Johansson; [2016]
    Nyckelord :finite element method; FEM; FEA; straightening of tube; arc height; ovalization; roller angle; plastic strain.;

    Sammanfattning : During this thesis work a coupled thermo-mechanical finite element model (FEM) was builtto simulate hot rolling in the blooming mill at Sandvik Materials Technology (SMT) inSandviken. The blooming mill is the first in a long line of processes that continuously or ingotcast ingots are subjected to before becoming finished products. LÄS MER
