Dynamic Contact Between a Rigid Indenter and a Kelvin-Voigt Half-Space

Following the theory developed by Ting, analytical expression of contact radius for an advancing contact is derived. For receding phase, contact radius is numerically obtained. Contact pressures for increasing and decreasing contacts are derived as a sum of two terms: the first is a Hertz-type pressure and the second term gives infinite pressure at the edge of the contact. Theoretical results are compared with the experimental data.
