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…
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…
Minimal resonances in annular non-Euclidean strips
Bryan Gin-ge Chen, Christian D. Santangelo
Differential growth processes play a prominent role in shaping leaves and biological tissues. Using both analytical and numerical calculations, we consider the shapes of closed, el…
Buckling Thin Disks and Ribbons with Non-Euclidean Metrics
Christian D. Santangelo
I consider the problem of a thin membrane on which a metric has been prescribed, for example by lithographically controlling the local swelling properties of a polymer thin film. W…
Rifts in Spreading Wax Layers
Rolf Ragnarsson, J. Lewis Ford, Christian D. Santangelo +1
We report experimental results on the rift formation between two freezing wax plates. The plates were pulled apart with constant velocity, while floating on the melt, in a way akin…
