3. 2. The interdependence of plastic behaviour and final properties of steel wire, analysed by the finite element method

   Författare :Henrik Överstam; Magnus Jarl; Sven-Erik Lundberg; Chunhui Luo; Örebro universitet; []
   Nyckelord :Technology; FEM; defects; steel wire; wire drawing; rolling; forging; Teknikvetenskap; TECHNOLOGY; TEKNIKVETENSKAP; Maskinteknik; Mechanical Engineering;

   Sammanfattning : The finite element method (FEM) has been used in order to study the interdependence of plastic behaviour and final properties in steel wire. Three processes metal forming have been studied: billet forging, wire rod rolling, and cold drawing. LÄS MER
