000015362 520__ $$2eng$$aIn the following, we examine the theoretical structure and numerical predictions of micropolar and Gurtin type models of higherorder single crystal plasticity. The models are discussed within a continuum thermodynamic setting, which facilitates identification of equivalent terms and their roles in the respective models. Finite element simulations are used to elucidate the various scale-dependent strengthening mechanisms and their effect of material response. Our analysis shows that the two theories contain many analogous features and qualitatively predict the same trends in mechanical behavior, in spite of substantially different points of departure. This is significant since the micropolar theory affords a simpler numerical implementation that is less computationally expensive.
