000015361 520__ $$2eng$$aIn this talk, the effect of sample size on the mechanical response of micron-sized crystals will be analysed using a mesoscopic model of field dislocation mechanics. The computational experiments performed using this field model show that the spatial distribution of statistical dislocation sources and polar dislocations, and dislocation accumulation along the grain boundaries and passivation layers, are responsible for these experimentally observed size effects. Continuum representation of the microscopic features, such as operation of dislocation sources and interaction of grain boundaries with dislocations, will also be discussed in this talk.
