| Abstract: | Based on plastic theory of powder compact and compressible rigid biscoplastic finite element method, a two dimensional simulation system PM 2DF was developed and the deformation and densification of powder compact are simulated. The simulation results discribe the rule of deformation, densification and mater flow, and they are consistent with the experimental results. |
