DESCRIPTION:Benoit Roman\, PMMH\, ESPCI\, Paris\nOur everyday experience o
 f tearing (fracture in thin sheets) can be frustrating (not-so-"easy openi
 ng" packages\, removing adhesive tape…).\nIn fact tearing paths are very
  reproducible and we will show that they obey simple laws\, with consequen
 ces in engineering at many scales\, including in many examples around us.\
 n\nIn this seminar\, I will review several tearing problems\, where exper
 imental fracture path are very robust. I will show how a simplistic (geome
 tric) framework\, based on energy arguments\, provides very insightful inf
 ormation. However\, a complete description should include additional effec
 ts\, and in particular anisotropy\, a consequence of the manufacturing of 
 thin sheets\; tearing a piece a paper brings us to deep questions in frac
 ture mechanics.\n\nBio:\nB. Roman is a senior CNRS scientist in Paris (PMM
 H\,ESPCI)\, working on then non-linear mechanics of slender bodies (tearin
 g\, crumpling\, wrinkling\, capillary folding\, morphing..).\nPhD in physi
 cs in Marseille\, Postdoc in Texas\, and in Chile\, joined CNRS in Paris a
 t ESPCI and teached mechanics in Ecole Polytechnique (Paris).\n
