Abstract

A microscopic model of an average dislocation velocity with dynamic effects and thermal activation process is presented. Combined with Alexander-Haasen's theory of multiple behavior of dislocations, a stress-strain curve is calculated. The results reproduce typical behavior at medium and elevated temperatures. In addition, as an anomaly caused by dynamic effects at cryogenic temperatures, the stress-strain cu+rve under cyclic superconducting-normal transition is simulated.
