Multilevel statistical model describing discontinuous dynamic recrystallization

Abstract

A physical multilevel statistical model of inelastic deformation has been developed taking into account discontinuous dynamic recrystallization. This model allows one to correctly describe the stress-strain state of the material as well as its evolving internal structure (grains, dislocations, and textures). Experiments on uniaxial compression of pure oxygen-free copper are used to identify and verify the results obtained. The developed model can be used to simulate technological processes in structural alloys.
