4. EHD linear contact lubrication
When the cylinders in contact are subjected to a high load, elastic deformation of the masses occurs. This is known as elastohydrodynamic lubrication (EHD).
4.1 Elastic deformation of solid bodies in contact

Hertz theory
Hertz theory can be used to calculate the elastic deformation and pressure field in the contact . Under load, the point or linear contact becomes a contact with an elliptical or rectangular surface. This surface is very small, resulting in a high...
