Abstract	A mathematical model of stress–strain behavior is developed for the process of powder wire flattening. Modeling was based on a partition of the deformation zone at a set of elementary volumes and a joint solution of the plasticity condition for porous materials and the equation of static equilibrium of forces within the elementary volume. The proposed mathematical model takes into account the real character of geometric parameter distributions as well as the complex of mechanical properties and conditions of contact friction along the length of the deformation zone. A distinctive feature of this model is an accounting for shell deformation in the deformation zone. This allowed us to define more precisely the plastic deformation zone and take into account the effect of shell bending on the energy-power parameters of the process. The experiments confirmed the validity of the assumptions and the shell influence on the process parameters. The proposed modeling approach provides the possibility to predict and optimize the parameters of an electrode material made by pressure working of powder wire. The derived results of the numerical simulation may be useful in improving the efficiency of the subsequent deposit welding operations.
