1. Elastohydrodynamic (EHD) regime
1.1 Lubricated hertzian contact
Hertzian contacts are those subjected to high Hertz pressures in excess of 200 MPa.
EHD lubrication occurs in contacts between non-conforming surfaces, which are subject to a punching effect: mainly between gear teeth, in bearings in contact with the track/rolling element, and in cam/push-button contacts.
It is also found in biomechanics, in the joints of the lower limbs. Contact pressure is generally very low (around 4 MPa when walking), but porous, water-rich cartilage has a very low Young's modulus of the order of 10 to 100 MPa (
