Abstract
The Bodner–Partom model is modified to describe such features of deformation as nonmonotonic dependence of hardening rate on stored plastic strain. This effect is allowed for by representing the hardening rate, which is a constant in the Bodner–Partom model, as a functional of plastic strain and plastic work. The Bodner–Partom parameters are found for some low-alloyed steels. The experimental and calculated data are in satisfactory agreement. The uniaxial deformation model is generalized to the case of multiaxial deformation
