Contact lines on stretched soft solids: Modeling anisotropic surface stresses
Stefanie Heyden, Nicolas Bain, Qin Xu +2
We present fully analytical solutions for the deformation of a stretched soft substrate due to the static wetting of a large liquid droplet, and compare our solutions to recently p…
Droplets sit and slide anisotropically on soft, stretched substrates
Katrina Smith-Mannschott, Qin Xu, Stefanie Heyden +3
Anisotropically wetting substrates enable useful control of droplet behavior across a range of applications. Usually, these involve chemically or physically patterning the substrat…
Viscoelastic and poroelastic relaxations of soft solid surfaces
Qin Xu, Lawrence A. Wilen, Katharine E. Jensen +2
Understanding surface mechanics of soft solids, such as soft polymeric gels, is crucial in many engineering processes, such as dynamic wetting and adhesive failure. In these situat…
Stress fluctuations and shear thickening in dense granular suspensions
Qin Xu, Abhinendra Singh, Heinrich M. Jaeger
We experimentally investigate the rheology and stress fluctuations of granules densely suspended in silicone oil. We find that both thickening strength and stress fluctuations sign…
Singular dynamics in the failure of soft adhesive contacts
Justin D. Berman, Manjari Randeria, Robert W. Style +6
We characterize the mechanical recovery of compliant silicone gels following adhesive contact failure. We establish broad, stable adhesive contacts between rigid microspheres and s…
Surface Elastic Constants of a Soft Solid
Qin Xu, Robert W. Style, Eric R. Dufresne
Solid interfaces have intrinsic elasticity. However, in most experiments, this is obscured by bulk stresses. Through microscopic observations of the contact-line geometry of a part…
