A method of computer simulation of the process of strain hardening in rods of circular cross-section subjected to deformation in a rolling–drawing process is presented. Such simulation allows the determination of the magnitude of the deformations induced by the rolling and drawing to obtain a particular cross-sectional hardness distribution in the rod. The application of this method permits, in particular, the determination of the conditions under which a rod subjected to combined rolling–drawing deformation will exhibit uniform hardness. The method was experimentally verified for Cu–30Zn rods.
