Notes:
The rolling compaction can produce porous or dense strips with special functions. Themechanical behaviors in rolling compaction are hard to predict accurately and efficiently bytraditional means. The numerical simulation based on the Finite Element Method (FEM) provides aflexible and efficient way for such problems. This paper introduces three-dimensional (3-D) FEMsimulations for the rolling compaction of the iron matrix powders. The elliptical yield criterion,elasto-plastic constitutive relationship and the friction model were analyzed. Simulations werebased on the second-developed user subroutine in MSC.Marc. Effects of friction and rollingvelocity on the rolling force, distribution of the density and some other parameters were analyzed
