At the end of a moving string
J. A. Hanna, C. D. Santangelo
One cannot pull an open, curved string along itself. This fact is clearly reflected in the unwrapping motion of a string or chain as it is dragged around an object, and implies str…
Slack Dynamics on an Unfurling String
J. A. Hanna, C. D. Santangelo
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, rectificati…
An Instability in a Straightening Chain
J. A. Hanna, H. King
We briefly discuss an arch-like structure that forms and grows during the rapid straightening of a chain lying on a table. This short note accompanies a fluid dynamics video submis…
Programmed buckling by controlled lateral swelling in a thin elastic sheet
M. A. Dias, J. A. Hanna, C. D. Santangelo
Recent experiments have imposed controlled swelling patterns on thin polymer films, which subsequently buckle into three-dimensional shapes. We develop a solution to the design pro…
