Dynamic strain aging: A coupled dislocation—Solute dynamic model

Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2005
Abstract A model for dynamic strain aging is proposed. It is written as a local constitutive formulation but can easily be extended to account for spatial interactions. The model is obtained by embedding accepted ‘slow’ time scale formulations for dislocation dynamics and aging kinetics in a multiple time scales dynamic system. Dislocation and solute

Constitutive model for metals with dynamic strain aging

Mechanics of Materials, 2019
Abstract In this paper, a modified constitutive relation to model the dynamic strain aging phenomenon is proposed based on the previous model of Voyiadjis-Abed. The dynamic strain aging phenomenon is typically observed in metals for a certain range of strain rates and temperatures.
