Anisotropic permeability and tortuosity in deformed wet sediments
Journal of Geophysical Research: Solid Earth, 1990Dewatering in many accretionary prisms is inferred to occur preferentially along discrete tectonic structures. However, these structures commonly consist of intense particle realignment in ductile shear zones rather than dilative fractures. Such realignment prompts a reduction in porosity within the zones, but there is, nevertheless, natural evidence ...

Electro‐Elastic Wetting: A Method to Migrate and Deform Droplets
Advanced Functional Materials, 2023AbstractA new wetting mechanism, termed electro‐elastic wetting, and methods to exploit it for droplet manipulation are proposed and demonstrated. The system consists of a droplet of dielectric liquid, an elastic and conductive membrane as its shell, and an electrode‐dielectric composite as its substrate.

Mechanism of wetting–induced deformation and failure of unsaturated soils
International Journal for Numerical and Analytical Methods in Geomechanics, 2022AbstractThe mechanisms of hydraulic collapse (wetting‐induced deformation) are studied through a series of simulations using a model for unsaturated soils. The model is a critical state soil model extended for unsaturated soils using Bishop's effective stress tensor, the state boundary surface (SBS) moving with the change in the degree of saturation ...

Behaviour of wet quartzite: deformation experiments revisited
2020<p>Since quartz is among the most abundant minerals in continental crust and one of the first to show plasticity with increasing pressure and temperature, understanding its mechanical behavior is crucial for estimates on crustal strength and modeling of geodynamic processes.

The wimple: A rippled deformation of a wetting film during its drainage
Physics of Fluids, 2007It has long been accepted that hydrodynamic pressure in a draining fluid film can cause inversion of curvature of a fluid-fluid interface, creating the so-called dimple. However, it was recently discovered that a different shape, dubbed a wimple, can be formed if a bubble/drop is initially in the field of repulsive surface forces, so that a wetting ...

Deformation of wet wood under combined shear and compression
Wood Science and Technology, 2005During refining of mechanical pulp, a process occurring at high speed at temperatures of 140-160 degrees C, the flexibility and bonding ability of wood fibres are increased.

Wet Adhesion of Micro-patterned Interfaces for Stable Grasping of Deformable Objects
2020 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2020Stable grip of wet, deformable objects is a challenging task for robotic grasping and manipulation, especially for food products' handling. The wet, slippery interfaces between the object and robotic fingers may require larger gripping force, resulting in higher risk of damaging the grasped object.

Orientation and deformation of wet-stretched all-cellulose nanocomposites
Journal of Materials Science, 2013Cellulose nanowhiskers (CNWs) are used to reinforce an all-cellulose composite. This composite comprises a matrix formed by dissolution of plant cellulose using a lithium chloride/N,N-dimethylacetamide solvent system into which high stiffness CNWs are dispersed.

The importance of shear zones in naturally deformed wet sediments
Tectonophysics, 1988Abstract The production of narrow shear zones was recently shown to be the chief mechanism by which wet argillaceous sediments deform in the laboratory. This article illustrates, by considering a variety of circumstances in which sediments deform, that this mode of deformation is of widespread importance in nature. Examples are given of shear zones,
