Wireless contact

Any contact subjected to high pressure, in excess of 200 MPa.

Elastohydrodynamic (EHD) regime

The EHD lubrication regime occurs in contacts between non-conforming surfaces, subject to a punching effect. The hydrodynamic equilibrium of the lubricant film is coupled with the elastic deformation of the surfaces in contact, hence the term "elastohydrodynamic".

Isotherm

Qualifies operation at constant temperature.

Isoviscous

A fluid whose viscosity does not depend on pressure.

Piezovisque

Refers to a fluid whose viscosity depends on pressure.

Newtonian fluid

Describes a fluid with purely viscous behavior....
