Onset Mechanism of Strain-Rate-Induced Flow Stress Upturn
The strain-rate response of flow stress in a plastically deforming crystal is formulated through a stress-sensitive dislocation mobility model that can be evaluated by atomistic simulation. For the flow stress of a model crystal of bcc Fe containing a [1 over 2] {111} screw dislocation, this approac...
