  1. 1. Analysis of hot workability in 316L steel using ductile fracture criterions

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Viktor Strid; [2022]
    Keywords : Ductile fracture criterion; Finite Element Method; Hot working; 316L Stainless Steel; Fracture Modeling; Gleeble; Hot deformation;

    Abstract : The focus of this thesis is to develop a simulation model for predicting ductile fractures during hot working at Alleima. The main fracture mechanism in these conditions is ductile fracture by void coalescence. The ductile fractures are caused by the linking of voids that appear when there is large plastic deformation near second-phase particles. READ MORE

  2. 2. 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

  4. 4. Simulation Method Development of Ultra Thick Laminates: : with Cohesive Zone Method and Empirical Arcan Tests

    University essay from KTH/Lättkonstruktioner

    Author : Jack Yan; [2011]
    Keywords : ;

    Abstract : To reduce the product life cost of aircrafts, the conversion of major load bearing components from aluminium to carbon fibre reinforced plastics have been proposed. Large load bearing components require significantly thicker composite laminates than conventional. READ MORE
