000015343 520__ $$2eng$$aCrystal plasticity at micron-nano scales involves many new interesting issues. The atypical plastic behavior at submicron scales cannot be effectively investigated by either traditional crystal plastic theory or large-scale molecule dynamics simulation. Accordingly, a discrete-continuous crystal plastic model is developed, which is coupling the discrete dislocation dynamics with finite element method. Three kinds of plastic deformation mechanisms for the single crystal pillar at submicron scale are investigated: (1) Single arm dislocation source controlled plastic flow; (2) Confined plasticity in coated micropillars; (3) Dislocation starvation under low amplitude cyclic loading. The predicted critical conditions of dislocation starvation agree well with the experimental data.
