Portevin–Le Chatelier effect: modeling the deformation bands and stress-strain curves

Abstract In the Portevin–Le Chatelier (PLC) effect sample plastic deformation takes place via localized bands. We present a model to account for band dynamics and the variability the bands exhibit. The approach is tuned to account for strain hardening and the strain-rate dependence for the case of s...
