Programming curvilinear paths of flat inflatables
Autor: Etienne Reyssat, José Bico, Benoît Roman, Emmanuel Siéfert
Publikováno v: Proceedings of the National Academy of Sciences of the United States of America
Proceedings of the National Academy of Sciences of the United States of America, National Academy of Sciences, 2019, 116 (34), pp.16692-16696. ⟨10.1073/pnas.1904544116⟩
International audience; Inflatable structures offer a path for light deployable structures in medicine, architecture, and aerospace. In this study, we address the challenge of programming the shape of thin sheets of high-stretching modulus cut and se

Guided tearing: The ruler test
Autor: J. F. Fuentealba, José Bico, Benoît Roman, Francisco Melo, Alejandro Ibarra
Publikováno v: Physical Review Materials
Physical Review Materials, American Physical Society, 2021, 5 (2), ⟨10.1103/PhysRevMaterials.5.025601⟩
The physical rules governing the tearing of a packaging or of a piece of paper are not completely elucidated despite being common phenomena in daily life. Here, we investigate how the presence of a straight rigid object, a ruler, guides the fracture

Nature of Crack Path Instabilities in Thin Sheets Cut by Blunt Objects
Autor: Iryna Sivak, Eugenio Hamm, Benoît Roman
Publikováno v: Physical Review Letters
Physical Review Letters, American Physical Society, 2020, 124 (17), ⟨10.1103/PhysRevLett.124.174101⟩
International audience; Cutting a brittle soft sheet with a blunt object leaves an oscillating crack that seemingly violates the principle of local symmetry for fracture. We experimentally find that at a critical value of a well chosen control parame

Elastocapillary adhesion of a soft cap on a rigid sphere

Publikováno v: Soft Matter
Soft Matter, Royal Society of Chemistry, 2020, 16 (8), pp.1961-1966. ⟨10.1039/c9sm02057h⟩
International audience; We study the capillary adhesion of a spherical elastic cap on a rigid sphere of a different radius. Caps of small area accommodate the combination of flexural and in-plane strains induced by the mismatch in curvature, and full

Physical Review Letters, 2020, ⟨10.1103/PhysRevLett.124.174102⟩
International audience; We report a new oscillatory propagation of cracks in thin films where three cracks interact mediated by two delamination fronts. Experimental observations indicate that delamination fronts joining the middlecrack to the latera

Programming stiff inflatable shells from planar patterned fabrics
Autor: Benoît Roman, José Bico, Emmanuel Siéfert, Etienne Reyssat

Soft Matter, Royal Society of Chemistry, 2020, ⟨10.1039/cXsm00000x⟩
Lack of stiffness often limits thin shape-shifting structures to small scales. The large in-plane transformations required to distort the metrics are indeed commonly achieved by using soft hydrogels or elastomers. We introduce here a versatile single

Geometry and mechanics of inextensible curvilinear balloons
Autor: José Bico, Emmanuel Siéfert, Benoît Roman, Etienne Reyssat
Publikováno v: Journal of the Mechanics and Physics of Solids
Journal of the Mechanics and Physics of Solids, Elsevier, 2020, 143, pp.104068. ⟨10.1016/j.jmps.2020.104068⟩
International audience; Mylar balloons are popular in funfairs or birthday parties. Their conception is very simple: two pieces of flat thin sheets are cut and sealed together along their edges to form a flat envelope. Inflation tends to deform this

Morphogenesis through elastic phase separation in a pneumatic surface
Autor: Benoît Roman, Emmanuel Siéfert
Publikováno v: Comptes Rendus Mécanique
Comptes Rendus Mécanique, Elsevier, 2020, 348 (6-7), pp.649-657. ⟨10.5802/crmeca.43⟩
International audience; We report a phenomenon of phase separation that relates in many aspects to Yves Couder's work: an inflatable architectured elastomer plate, expected to expand homogeneously in its plane, buckles instead widely out-of-plane int
