Elasto-Hydrodynamic Propulsion of a Magnetically Actuated Filament
Sohum Kapadia, Julien Chopin, Arshad Kudrolli
We investigate the low-Reynolds-number propulsion of a slender elastic filament with a dipolar magnetic head actuated by an oscillating field in a viscous fluid by studying its str…
Bundling architecture in elastic filaments with applied twist
Amit Dawadi, Animesh Biswas, Julien Chopin +1
We investigate the formation of helical multifilament bundles and the torque required to achieve them as a function of applied twist. Hyperelastic filaments with circular cross sec…
Energetics of twisted elastic filament pairs
Julien Chopin, Animesh Biswas, Arshad Kudrolli
We investigate the elastic energy stored in a filament pair as a function of applied twist by measuring torque under prescribed end-to-end separation conditions. We show that the t…
Tensional twist-folding of sheets into multilayered scrolled yarns
Julien Chopin, Arshad Kudrolli
Twisting sheets as a strategy to form functional yarns relies on millennia of human practice in making catguts and fabric wearables, but still lacks overarching principles to guide…
Universal scaling of the velocity field in crack front propagation
Clément Le Priol, Julien Chopin, Pierre Le Doussal +2
The propagation of a crack front in disordered materials is jerky and characterized by bursts of activity, called avalanches. These phenomena are the manifestation of an out-of-equ…
Birth and decay of tensional wrinkles in hyperelastic sheets
Andreea Panaitescu, Meng Xin, Benny Davidovitch +2
We demonstrate with experiments that wrinkling in stretched latex sheets occur over finite strains, and that their amplitudes grow and then decay to zero over a greater range of ap…
