Probing Microplasticity in Small-Scale FCC Crystals via Dynamic Mechanical Analysis
Probing Microplasticity in Small-Scale FCC Crystals via Dynamic Mechanical Analysis
In small-scale metallic systems, collective dislocation activity has been correlated with size effects in strength and with a steplike plastic response under uniaxial compression and tension. Yielding and plastic flow in these samples is often accompanied by the emergence of multiple dislocation avalanches. Dislocations might be active preyield, but their …
