Abstract: The cross wedge rolling (CWR) process is studied with the
aid of 3-dimension rigid-plastic and coupled thermo-mechanical FEM. On
the platform of the general non-linearity FEM software Deform-3D,
3-dimension rigid-plastic and thermo-mechanical finite element model has
been established. Based on simulation results, temperature variation of
workpiece is analyzed during the rolling process. It also shows the
distributions of stress field in the different directions. They have
theoretical guide and significance further to investigate the
microstructural evolution law and predict accurately on comprehensive
mechanical property of CWR product.
Key words: Cross wedge rolling Finite element method
