    6.1 Rigid isoviscous (RI), rigid piezoviscous (RP), elastic isoviscous (EI) and elastic piezoviscous (EP) regimes

    To date, we have studied the EHD theory associated with a so-called piezoviscous elastic regime, i.e. with elastic surface deformation far greater than the lubricant film thickness, and lubricant viscosity increasing sharply in the contact.

    The field of application of EHD theory can be extended by defining three other regimes
