Based on the plastic deformation theory of porous metal material and the compressible rigid-plastic finite element theory of volume, a finite element formula suitable for analyzing the plastic deformation of porous metal was derived and the plastic deformation process of porous metal was numerically simulated . The effects of friction factor, aspect ratio, mold type and workpiece shape on the plastic deformation of porous metal were analyzed.
