  1. 1. 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

  3. 2. Numerical Prediction of the Cracks Effect on the Square Origami Tube

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Tianchen Feng; [2013]
    Nyckelord :Thin-walled tube; Origami pattern; Energy absorption; Cracks; ABAQUS; FEM;

    Sammanfattning : The energy absorption devices play important roles to reduce injures when the traffic accident happens. As a popular design, Thin-walled tube has been widely used in many industrial productions such as vehicles, ships and trains due to their high manufacturability and low cost. LÄS MER

  4. 3. Origami Pattern Tube for Vehicle Crash Box

    Kandidat-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Chengqi Li; Xin Li; Siqi Li; Sicong Ma; [2013]
    Nyckelord :Crash Box; Energy Absorption Device; Elastic-ideal Plastic; Finite Element Modelling; Manufacturing Techniques; Origami Pattern; Thin-walled Tube;

    Sammanfattning : With an increasing number of traffic accidents, more and more people are injuring or even dying during the collision. One of the main reasons is frontal collisions. Therefore, the safety system is a very important part of the vehicle. LÄS MER
