Fundamentals and Advances in Elastohydrodynamics: The Role of Ramsey Gohar

This paper commemorates Ramsey Gohar by acknowledging his contributions to the fields of contact mechanics and elastohydrodynamic lubrication (EHL) within context developments these subjects. A historical discourse is provided on elastohydrodynamics, from its inception in 1940s present. We demonstrate that was not only a pioneer discoveries fundamentals subject, but also led or contributed significantly continual advances understanding EHL diverse applications.
