DESCRIPTION:Dr. Corentin Coulais\, FOM Institute AMOLF\, Amsterdam\, Nethe
 rlands\nBio : Corentin Coulais is a Post-doctoral fellow at the FOM Instit
 ute AMOLF in Amsterdam. His research focuses on the understanding of the m
 echanics and the physics of soft structured materials. C. Coulais received
  a B.Sc. (2006) and a M.Sc. (2009) in Physics from Ecole Normale Supérieu
 re de Lyon\, and a Ph.D. in Physics from University of Paris VI (2012). He
  then obtained a Post-Doc position at Leiden University in the Netherlands
  (2013-2015) and a VENI grant (Netherlands Organization for Scientific Res
 earch) to join the FOM Institute AMOLF (2016-). More information about his
  activities can be found at http://corentincoulais@wordpress.com\nAbstract
  :\nDue the recent advent of 3D printing\, the last few years have seen a 
 revolution in artificial periodic composites with extremely tunable electr
 omagnetic\, acoustic\, thermal and mechanical properties\, which cannot be
  found in nature and which find multiple applications in detection\, cloak
 ing and energy harvesting devices. Most of these so-called metamaterials e
 xhibit a linear response which simplifies the problem of their design but 
 limits the scope of realizable properties. Yet\, metamaterials become part
 icularly interesting in mechanics\, where nonlinear response is much more 
 accessible and stronger than in any other physical field. In this talk\, I
  will show that mechanical metamaterials using geometrical nonlinearities 
 and mechanical instabilities lead to entirely new properties and functiona
 lities such as elastic memory\, negative stiffness and programmable respon
 se. Using 3D printing of flexible materials\, precision desktop experiment
 s\, numerical modeling and theory\, we demonstrate that flexible metamater
 ials can be designed\, fabricated and programmed for specific mechanical t
 asks. Such approach opens up promising pathways to bridge the gap between 
 Matter and Machine.
