The powder-cored wire drawing process is simulated using the finite-element method. To describe the behavior of the powder core, a plasticity model of porous and granular media with planar defects is proposed. The model takes into account bimodulus behavior and susceptibility to dilatancy. The densification of the powder core after one and six wire-drawing passes is studied. Substantial transverse nonuniformity in the density distribution of the powder core is found. The dependence of the densification behavior of the powder core on the initial porosity and fraction of planar effects is established.
