Dynamics of drag and force distributions for projectile impact in a granular medium
Massimo Pica Ciamarra, Antonio H. Lara, Andrew T. Lee +3
Our experiments and molecular dynamics simulations on a projectile penetrating a two-dimensional granular medium reveal that the mean deceleration of the projectile is constant and…
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…
Localization and extinction of bacterial populations under inhomogeneous growth conditions
Anna L. Lin, Bernward A. Mann, Gelsy Torres-Oviedo +3
The transition from localized to systemic spreading of bacteria, viruses and other agents is a fundamental problem that spans medicine, ecology, biology and agriculture science. We…
Steady state velocity distributions of an oscillated granular gas
Sung Joon Moon, J. B. Swift, Harry L. Swinney
We use a three-dimensional molecular dynamics simulation to study the single particle distribution function of a dilute granular gas driven by a vertically oscillating plate at hig…
Kink-induced transport and segregation in oscillated granular layers
Sung Joon Moon, Daniel I. Goldman, J. B. Swift +1
We use experiments and molecular dynamics simulations of vertically oscillated granular layers to study horizontal particle segregation induced by a kink (a boundary between domain…
