Capillary fracture of soft gels
Joshua B. Bostwick, Karen E. Daniels
A liquid droplet resting on a soft gel substrate can deform that substrate to the point of material failure, whereby fractures develop on the gel surface that propagate outwards fr…
Self-healing Dynamics of Surfactant Coatings on Thin Viscous Films
Stephen L. Strickland, Matthew Hin, M. Richard Sayanagi +3
We investigate the dynamics of an insoluble surfactant on the surface of a thin viscous fluid spreading inward to fill a surfactant-free region. During the initial stages of surfac…
Correlations between electrical and mechanical signals during granular stick-slip events
Karen E. Daniels, Caroline Bauer, Troy Shinbrot
Powders and grains exhibit unpredictable jamming-to-flow transitions that manifest themselves on geophysical scales in catastrophic slip events such as landslides and earthquakes,…
Surfactant Spreading on a Thin Liquid Film: Reconciling Models and Experiments
Ellen R. Swanson, Stephen L. Strickland, Michael Shearer +1
The spreading dynamics of surfactant molecules on a thin fluid layer is of both fundamental and practical interest. A mathematical model formulated by Gaver and Grotberg 1990 descr…
Local properties of patterned vegetation: quantifying endogenous and exogenous effects
G. G. Penny, K. E. Daniels, S. E. Thompson
Dryland ecosystems commonly exhibit periodic bands of vegetation, thought to form due to competition between individual plants for heterogeneously distributed water. In this paper,…
