A classification of stress anomaly mechanisms was proposed which was based upon 2 limiting cases; according to whether the macroscopic behaviour directly reflected individual dislocation properties, or involved the entire dislocation population. It was shown that, in the second case, some typical anomalies could be defined according to the relative efficiencies of the mechanisms which were responsible for an increase or decrease in the mobile dislocation density. They were associated with specific strain-rate sensitivities.
