000015342 520__ $$2eng$$aIn small scale plasticity, size-effects have been observed in nearly every miniaturized materials test. In the current contribution we present crystal plasticity finite element simulations of several small scale tests, employing the so-called continuum dislocation dynamics as constitutive law. The resulting materials response and local dislocation evolution are compared to according experiments and discrete dislocation simulations from the literature. We demonstrate that crystal plasticity laws based on continuum dislocation dynamics are able to predict various kinds of size-effects, whether they relate to strain gradients (micro-bending), dislocation line-tension (thin film bending) or dislocation starvation (micro compression).
