Paper: J. A. Hanna and C. D. Santangelo, « Slack Dynamics on an Unfurling String », Phys. Rev. Lett. 109, 134301 (2012)

Abstract: An arch will grow on a rapidly deployed thin string in contact with a rigid plane. We present a qualitative model for the growing structure involving the amplification, rectification, and advection of slack in the presence of a steady stress field, validate our assumptions with numerical experiments, and pose new questions about the spatially developing motions of thin objects.
