Abstract：Numerical simulation has become an effective tool in research and application of the powder compaction process. The mechanical modeling methods，the typical yield models and the material parameters （e.g.Young’s modulus，Poisson’s ratio and flow stress） used in the finite element simulation of powder compaction process were summarized. In addition，several softwares commonly used in this field，such as MSC.Marc，ABAQUS，DEFORM and ANSYS were compared in detail. Based on the current research situation，the future of simulation technique in powder metallurgy field was expected，and the primary development directions was pointed out，which were establishing more accurate mathematical models，enhancing 3D simulation and multi-fields coupling ability，applying software secondary development technology and improving numerical precision and practicality.
