Fig. 2From: Portevin–Le Chatelier effect: modeling the deformation bands and stress-strain curvesa The strain evolution of the expected average hardening coefficient 〈h〉 (blue) and the local hardening parameter values from one simulation (grey). The drops in the local hardening coefficient signify increases in the local plastic strain due to passing of bands. b The strain rate dependence of the parameter \(D=D_{0} \epsilon _{ext, t}^{\gamma }\)Back to article page
