We show that an extension of Ananthakrishna's (AK) model exhibits all the features of the Portevin-Le Chatelier (PLC) effect including the recently observed crossover from a low dimensional chaotic state at low and medium strain rates to a high dimensional power law state of stress drops at high str

The PortevinLe Chatelier effect is assumed to be associated with an inverse strain-rate effect. A numerical analysis of a rheological model is then conducted, where a dashpot is assumed to exhibit a stress versus strain-rate relation with a region of negative slope, i.e. an inverse strain-rate effec
