Pressure Dependence of the Contact Angle
The Journal of Physical Chemistry B, 2007When a liquid and its vapor contact a smooth, homogeneous surface, Gibbsian thermodynamics indicates that the contact angle depends on the pressure at the three-phase line of an isothermal system. When a recently proposed adsorption isotherm for a solid-vapor interface is combined with the equilibrium conditions and the system is assumed to be in a ...

Effects of pressure on contact dermatitis
American Journal of Industrial Medicine, 1985AbstractIn human volunteers, firm pressure was applied to deformable plastic chambers containing (1) chemical irritants, (2) glass fibers, and (3) selected allergens to which the subjects were sensitive.Pressure variably intensified irritant dermatitis and strikingly enhanced fiberglass dermatitis. Pressure did not influence allergic contact dermatitis.

Contact in the honing of cylindrical holes is simulated. Nonlinear behavior of the mean contact pressure and the transfer coefficient is observed. These factors depend on the applied force and the surface relief, as well as the materials used in the tool and workpiece.

Contact Force Decomposition Using Contact Pressure Distribution
IEEE Robotics and Automation Letters, 2017Many robotics applications involving contact with objects require the decomposition of an external force measured by a force sensor into its normal and shear components. In this paper, we present a general and effective contact force decomposition method based on the contact pressure distribution.

Distribution of contact pressure in wheel–rail contact area
Wear, 2002Abstract The authors have recently assessed the feasibility of applying an ultrasonic technique for investigating contact problems between the wheel and rail. In particular, the size and shape of the contact area have been determined, obtaining good agreement between the experimental data and Hertz’s theory.

Intraocular pressure with miniscleral contact lenses
Vestnik oftal'mologii, 2021According to literature data, some experts do not exclude the possibility that scleral lens wear could influence intraocular pressure.To evaluate the influence of rigid gas permeable miniscleral contact lenses on intraocular pressure (IOP), keratometry readings and corneal thickness, and to study the correlation between scleral (IOPs) and corneal (IOPc)

The consequences of contact pressure in phyllotaxis
Journal of Theoretical Biology, 1977Abstract To determine the consequences of contact pressure in phyllotaxis, a mathematical model is constructed in which a leaf distribution is represented by a point lattice of n + 1 lattice points at equal intervals on a helix wound around a cylinder.

113 pages ; Supplemental file(s) description: None. ; Pressure field contact (PFC) generalizes the flat Winkler elastic foundation model to contact situations with arbitrary, non-convex, coarsely meshed solid geometries. PFC calculates the deformed contact surface, the traction distribution on that surface, and, consequently, the net wrench (the net ...

Superconductive Pressure Contacts
Journal of Applied Physics, 1968Superconductive contacts are nearly as old as superconductivity itself; in 1914, only three years after he had discovered superconductivity, Kamerlingh-Onnes1 found that a Pb–Pb contact carried supercurrents. Significantly, extreme cleaning of the contact surfaces was not necessary.
