In the classical (rate-independent)
theory of metal plasticity, the plastic spin has been an issue of
research and debate for about thirty years. Judging by the content
of current publications on the topic (regarding modeling
possibilities, consequences and applications), it seems that the
concept has acquired a certain degree of acceptance, although no
rigorous justification, at theoretical level, has ever been provided.
In the attached preprint this matter is investigated starting from
