DESCRIPTION:Prof. Benoît Roman\nWhen opening a package\, one would like t
 o propagate tearing cracks along paths that will allow to easily extract t
 he content.\nBut sometimes we have the frustrating feeling that cracks in 
 thin sheets follow their own will (think about peeling a piece of adhesive
  tape\, or removing wallpaper).\nI will review recent works which show tha
 t Indeed quasistatic cracks follow remarkably reproducible paths in thin s
 heet. I will try to demonstrate some of the experiments during the talk an
 d give a simplified framework that can be used to predict these trajectori
 es\, and possible applications.\n\nReferences :\nE.Hamm\, P.M.Reis\, M.Leb
