Oscillating membranes: modeling and controlling autonomous shape-transforming sheets
Ido Levin, Robert Deegan, Eran Sharon
Living organisms have mastered the dynamic control of internal stresses to perform an array of functions, such as change shape and locomote. State-of-the-art attempts to replicate…
Semi-implicit methods for the dynamics of elastic sheets
Silas Alben, Alex A. Gorodetsky, Donghak Kim +1
Recent applications (e.g. active gels and self-assembly of elastic sheets) motivate the need to efficiently simulate the dynamics of thin elastic sheets. We present semi-implicit t…
Rayleigh-Plateau instability causes the crown splash
Robert D. Deegan, Philippe Brunet, Jens Eggers
The impact of a drop onto a liquid layer and the subsequent splash has important implications for diverse physical processes such as air-sea gas transfer, cooling, and combustion.…
Persistent holes in a fluid
Florian S. Merkt, Robert D. Deegan, Daniel I. Goldman +2
We observe stable holes in a vertically oscillated 0.5 cm deep aqueous suspension of cornstarch for accelerations a above 10g. Holes appear only if a finite perturbation is applied…
Cracks in rubber under tension exceed the shear wave speed
Paul J. Petersan, Robert D. Deegan, M. Marder +1
The shear wave speed is an upper limit for the speed of cracks loaded in tension in linear elastic solids. We have discovered that in a non-linear material, cracks in tension (Mode…
Oscillating Fracture in Rubber
Robert D. Deegan, Paul J. Petersan, M. Marder +1
We have found an oscillating instability of fast-running cracks in thin rubber sheets. A well-defined transition from straight to oscillating cracks occurs as the amount of biaxial…
