… We demonstrate strain-rate sensitivity emerging in single-crystalline Cu nanopillars with … at different constant strainrates. In the range of pillar diameters and strainrates tested, we find …
… for nucleation involves the … dislocationnucleation and dislocation motion can be readily understood through atomistic simulations. Here, we focus our attention on dislocationnucleation …
… However, a sudden increase in strainrate to 10 −3 s −1 causes a noticeable surge in dislocation density as the nucleationrate outweighs the loss rate. This observation indicates that …
