Comparison between step strains and slow steady shear in a bubble raft
Michael Twardos, Michael Dennin
We report on a comparison between stress relaxations after an applied step strain and stress relaxations during slow, continuous strain in a bubble raft. A bubble raft serves as a…
Velocity Fluctuations in a Slowly Sheared Bubble Raft
Michael Dennin
A surprising feature of flow in slowly sheared model foam (bubble raft) is a measured discontinuity in the rate of strain as a function of position such that part of the system is…
Slow Steady-Shear of Plastic Bead Rafts
Michael Twardos, Michael Dennin
Experimental measurements of the response of a two dimensional system of plastic beads subjected to steady shear are reported. The beads float at the surface of a fluid substrate a…
Statistics of Bubble Rearrangements in a Slowly Sheared Two-dimensional Foam
Michael Dennin
Many physical systems exhibit plastic flow when subjected to slow steady shear. A unified picture of plastic flow is still lacking; however, there is an emerging theoretical unders…
Dislocation Dynamics in an Anisotropic Stripe Pattern
Carina Kamaga, Fatima Ibrahim, Michael Dennin
The dynamics of dislocations confined to grain boundaries in a striped system are studied using electroconvection in the nematic liquid crystal N4. In electroconvection, a striped…
