Journal of Fluid Science and Technology, 2023 We introduced a core-flooding test equipment with the triaxial cell having been made available to in situ computed tomography (CT) scanning. Water flow-through tests were conducted on 38 mm-diameter fractured granite cores containing either saw-cut or ...

Adhesion Between Rigid Indenter and Soft Rubber Layer: Influence of Roughness
Frontiers in Mechanical Engineering, 2020 We report a series of experiments on the indentation of steel indenters into a soft layer of transparent rubber with relatively high adhesion. The roughness properties of the steel indenters are varied by undergoing preparation using sandpaper with ...

Mechanics Analysis of Rough Surface Based on Shoulder-Shoulder Contact
Applied Sciences, 2021 Proper methods and models for mechanical analysis of rough surface can improve the theory of surface contact. When the topography parameters of two rough surfaces are similar, the contact should be considered shoulder-shoulder rather than top-top.

Surface Hierarchy: Macroscopic and Microscopic Design Elements for Improved Sliding on Ice
Lubricants, 2021 Frictional interaction with a surface will depend on the features and topography within the contact zone. Describing this interaction is particularly complex when considering ice friction, which needs to look at both the macroscopic and microscopic ...

Evaluation of the real contact area in three-body dry friction by micro-thermal analysis [PDF]
, 2009 Many tribological properties and wear mechanisms occurring on the micro-and nanoscale are strongly controlled by the so-called real contact area (Ar) which is a small fraction of the nominal or apparent contact area (Aa). The determination of Ar is often

High-Precision Tribometer for Studies of Adhesive Contacts
Sensors, 2023 Herein, we describe the design of a laboratory setup operating as a high-precision tribometer. The whole design procedure is presented, starting with a concept, followed by the creation of an exact 3D model and final assembly of all functional parts. The

Finite element based surface roughness study for ohmic contact of microswitches [PDF]
, 2012 Finite element method (FEM) is used to model ohmic contact in microswitches. A determinist approach is adopted, including atomic force microscope (AFM) scanning real contact surfaces and generating rough surfaces with three-dimensional mesh.

Contact area interaction with sliding widgets [PDF]
Proceedings of the 22nd annual ACM symposium on User interface software and technology, 2009 We show how to design touchscreen widgets that respond to a finger's contact area. In standard touchscreen systems a finger often appears to touch several screen objects, but the system responds as though only a single pixel is touched. In contact area interaction all objects under the finger respond to the touch. Users activate control widgets by sliding

The effect of contact area on the permeability of fractures [PDF]
Journal of Hydrology, 1992 Abstract The permeability of a rock fracture is controlled primarily by the geometry of its void space. One effect of void space geometry is to cause the fluid to follow a tortuous path to flow around the asperities, which are regions where the two faces of the fracture are in contact.
