Mechanics and energetics of electromembranes
Hadrien Bense, Benoît Roman, Bruno Andreotti
The recent discovery of electro-active polymers has shown great promises in the field of soft robotics, and was logically followed by experimental, numerical and theoretical develo…
Morphogenesis through elastic phase separation in a pneumatic surface
Emmanuel Siéfert, Benoît Roman
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…
Programming stiff inflatable shells from planar patterned fabrics
Emmanuel Siéfert, Etienne Reyssat, José Bico +1
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 us…
Pendulums, Drops and Rods: a physical analogy
Benoît Roman, Cyprien Gay, Christophe Clanet
A liquid meniscus, a bending rod (also called elastica) and a simple pendulum are all described by the same non-dimensional equation. The oscillatory regime of the pendulum corresp…
A new failure mechanism in thin film by collaborative fracture and delamination: interacting duos of cracks
Joel Marthelot, Jose Bico, Francisco Melo +1
When a thin film moderately adherent to a substrate is subjected to residual stress, the cooperation between fracture and delamination leads to unusual fracture patterns, such as s…
Self-replicating cracks: a collaborative fracture mode in thin films
Joel Marthelot, Benoit Roman, Jose Bico +3
Straight cracks are observed in thin coatings under residual tensile stress, resulting into the classical network pattern observed in china crockery, old paintings or dry mud. Here…
