Topological structure and dynamics of three dimensional active nematics
Guillaume Duclos, Raymond Adkins, Debarghya Banerjee +13
Point-like motile topological defects control the universal dynamics of diverse two-dimensional active nematics ranging from shaken granular rods to cellular monolayers. A comparab…
How super-tough gels break
Itamar Kolvin, John M. Kolinski, Jian Ping Gong +1
Fracture of highly stretched materials challenges our view of how things break. We directly visualize rupture of tough double-network (DN) gels at >50\% strain. During fracture, cr…
Nonlinear focusing in dynamic crack fronts and the micro-branching transition
Itamar Kolvin, Jay Fineberg, Mokhtar Adda-Bedia
Cracks in brittle materials produce two types of generic surface structures: facets at low velocities and micro-branches at higher ones. Here we observe a transition from faceting…
Crack front dynamics: the interplay of singular geometry and crack instabilities
Itamar Kolvin, Gil Cohen, Jay Fineberg
When fast cracks become unstable to microscopic branching (micro-branching), fracture no longer occurs in an effective 2D medium. We follow in-plane crack front dynamics via real-t…
Experimental Study of Energy Transfer by Inertial Waves During the Build up of Turbulence in a Rotating System
Itamar Kolvin, Kobi Cohen, Yuval Vardi +1
We study the transition from fluid at rest to turbulence in a rotating water cylinder. We show that the energy, injected at a given height, is transported by inertial wave packets…
