Hollow Needle Puncture Mechanics for Biopsy Sampling
Yiting Wu, Frederic Lechenault, Matteo Ciccotti +1
Biopsy sampling relies on hollow needles that puncture soft tissues by propagating and opening a cylindrical crack, yet the mechanics governing this coring process remain only part…
Soft coring: how to get a clarinet out of a flute?
Frederic Lechenault, Iyad Ramdane, Sebastien Moulinet +2
Cutting mozzarella with a dull blade results in poorly shaped slices: the process occurs in a configuration so deformed as to yield unexpectedly curved surfaces. We study the rich…
Dynamically writing coupled memories using a reinforcement learning agent, meeting physical bounds
Théo Jules, Laura Michel, Adèle Douin +1
Traditional memory writing operations proceed one bit at a time, where e.g. an individual magnetic domain is force-flipped by a localized external field. One way to increase materi…
KnitCity: a machine learning-based, game-theoretical framework for prediction assessment and seismic risk policy design
Adèle Douin, J. P. Bruneton, Frédéric Lechenault
Knitted fabric exhibits avalanche-like events when deformed: by analogy with eathquakes, we are interested in predicting these "knitquakes". However, as in most analogous seismic m…
The delicate memory structure of origami switches
Théo Jules, Austin Reid, Karen E. Daniels +2
While memory effects emerge from systems of wildly varying length- and time-scales, the reduction of a complex system with many interacting elements into one simple enough to be un…
Curving Origami with Mechanical Frustration
Théo Jules, Frédéric Lechenault, Mokhtar Adda-Bedia
We study the three-dimensional equilibrium shape of a shell formed by a deployed accordion-like origami, made from an elastic sheet decorated by a series of parallel creases crosse…
