Structural-scale levels of plastic deformation and fracture in the neck of polycrystals under tension.

The article discusses the analysis of processes of neck formation and viscous fracture with the multilevel relation between the plastic flow and structure. The study aims to investigate the laws of plastic flow at the macroscale and mesascale levels through local characteristics of strain measurement and constructing the distribution patterns. The author concludes that the central neck volume is the most favorable for the development of cracks because of high intensity in both symmetric.
