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.

Capillary pressure, osmotic pressure and bubble contact areas in foams
Soft Matter, 2021The capillary pressure of foams and emulsions is the difference between the average pressure in the dispersed phase and the pressure in the continuous phase.

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 ...

Contact pressure in indented elastohydrodynamic lubrication contacts
Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2008Indents perturb the pressure and stress distribution and increase the failure risk. Existing theory for roughness deformation is extended to pure-rolling elastohydrodynamic lubrication indented contact pressure perturbations. First, a study of shallow indents is proposed, then it is modified to account for non-linear behavior of deeper indents.

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.

Finger joint contact areas and pressures
Journal of Orthopaedic Research, 1985AbstractAlthough the joints of the index finger are similar geometrically and kinematically, the occurrence of degenerative joint disease is more frequent and severe in the distal interphalangeal joint. Much circumstantial evidence exists to suggest a mechanical cause for the observed differences in frequency.

Contact Pressure and Stress Distribution
1995A foundation is the interface between a structural load and the ground. The stress q applied by a structure to a foundation is often assumed to be uniform. The actual pressure then applied by the foundation to the soil is a reaction, called the contact pressure p and its distribution beneath the foundation may be far from uniform.

Effect of surface dents on contact pressure in elastohydrodynamic contacts
Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2009Nowadays film thickness measurement techniques can provide precise data for the detailed studies of the behaviour of lubricated contacts including transient operational conditions. Contact pressure is in relation with deformation of rubbing surfaces, which can be derived from experimentally evaluated film thickness.
