Abstract
Using the finite element method, we study the cyclic single slip of well-oriented ferritic grains at the surface of a polycrystal. We explain some usual observations, such as an increased plastic strain and a reduced number of activated slip systems. But these computations, which do not consider a smoother hardening near the free surface, seem to underestimate the real surface effect.
