Nonlinear Physics Seminar: "Geometry and mechanics of folding thin plates"

Wed, 17/03/2021 12:00 to 13:30
Lecturer: Prof. Mokhtar Adda-Bedia from Ecole Normale Superieure de Lyon, France    

Over the past thirty years, the ancient art of paper folding, or origami, has evolved into an

interdisciplinary scientific field. Origami offers the possibility for new metamaterials whose overall mechanical properties can be programmed by acting locally on each crease. Origami metamaterials show for example auxetic behaviour (negative Poisson ratio) and multistability, the latter allowing reprogrammable configurations and deployable structures. Starting from a thin plate and knowing the properties of the material and the folding procedure, one would like to determine the shape taken by the structure at rest and its mechanical response.
During this talk, I will review some recent experimental and theoretical developments on the physics and mechanics of origami-based metamaterials.
