Notes:
Material behaviors of anisotropy and rate sensitivity affect cold ring rolling greatly. So, aself-developed incremental model of rate dependent crystal plasticity (RDCP) is utilized to forecastthe deformation characteristics of this forming process based on a 3D FE model underABAQUS/Explicit environment. The results show that the model of RDCP captures materialbehaviors of anisotropy and rate sensitivity better in this forming process by the comparison with themodel of J2 plasticity; with the decrease of rate sensitivity coefficient, the forming process becomesmore unstable with smaller rolling force and growth in ring radial direction; with the increase of feedrate of idle roll, the deformation of ring becomes more even while the rolling force becomes larger
