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
