Plastic strain localization kinetics in vanadium
2020
In this work, the macroscopic strain localization in polycrystalline vanadium via the real-time digital image speckle correlation method under uniaxial tension was investigated. The plastic flow localization parameters were evaluated at various strain hardening stages. It is finally established that the yield point undergoes the motion of two localized strain fronts identical to the Luders bands and the parabolic strain hardening is characterized by stationary plastic strain bands.
