DESCRIPTION:The structural mechanics of shape-changing structures: from be
 nding armadillos\, self-deploying satellites\, to roll-up displays.\n\nMos
 t structures\, e.g. buildings & bridges\, are designed to be near rigid wh
 en loaded: in view of high winds or heavy traffic\, their movements are ba
 rely noticeable.  Formally\, they are stiff\, strong and stable\, in terms
  of their “structural mechanics” – the study of their loaded deforma
 tion.  Large movements from material weakness\, overloading\, or bad desig
 n\, typically portend failure & eventual collapse.  Embracing large moveme
 nts\, i.e. deliberate changes in shape\, can admit new behaviour if safe a
 nd reversible\, to yield transformer-like technologies and simple explanat
 ions of biological morphology\, for example.  In this talk\, I will descri
 be several structural mechanics principles for making shape-changing struc
 tures\, out of ordinary materials\, complete with physical demonstrations.
