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

    University essay from Högskolan Dalarna/Materialteknik

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

    Abstract : 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. READ MORE
