In [1] a variational formulation for this theory has been successfully provided in the context of special fields of bounded variation.\nTaking into account that many natural and man-made physical systems have a rich enough geometr ical structure to permit the identification of hierarchies consisting of m ore than one physically meaningful submacroscopic level\, the mechanical t heory of structured deformations has been enriched in [3]. This talk aims at presenting a variational framework of these latter theoretical setting s.\n\n\nReferences:\n\n[1] R. Choksi and I.
