This contribution complete a previous one (1) in that the specific problems of the elastoplastic behaviour of body-centered polycrystals are analyzed. The experimental results (yield stress, Lankford's ratio, textures, ...) are compared with those of self-consistent and Taylor modelling codes. A particular attention is put on the influence of the selection of glide systems in the framework of crystallographic or non-crystallographic assumptions.
