The progress of FEM simulation for metal deformation process is reviewed. The main theory of rigid （visco）-plastic FEM is dealt with. Based on the former constitutive model, the calculation formulas for rigid （visco）-plastic FEM are obtained. The computer system of FEM numberical simulation is also discussed. Finally, the prospects of the applications of FEM simulation to metal deformation are predicted.
