Interpretation of Strain Rate Effect of Metals

  • First Online:
Dynamic Behavior of Materials, Volume 1

Abstract

Mesoscopic mechanism of strain rate effect of metals has been discussed based on dislocation theory. Strain rate effect and dislocation motion is bridged by using the decomposition of strain rate, Orowan’s relationship and the stress dependence of dislocation velocity. The mechanism of strain rate effect has then been investigated qualitatively by using these three relationships. The process of strain rate effect has been well explained and some details of strain rate effect have been adequately discussed. These discussions are consistent with experiments.
