【Abstract】 With a geometrical model of porous materials, 3D finite-element analysis on the rolling process of 60Si2Mn in the semi-solid state was carried out using the software MARC. In terms of flat and groove rolling conditions, the stress field and strain field were studied. During groove rolling, the distributions of stress and strain on the cross-section of the deformation zone is more uniform than those during flat rolling. Simulation results are good agreement with experiment data, and show that semi-solid material is suitble for groove rolling.更多还原
