Witryna2 mar 2024 · An EHL Film Thickness Calculator allows calculating central and minimum film thicknesses in a full film lubricated elliptical (point) contact as a function of entrainment speed. The central and minimum film thicknesses are calculated using equations developed by Hamrock & Dowson [1], Chittenden et al [2] and … Witryna1. Contact Mechanics – Fully Elastic Models Hertz analyzed the stresses at the contact of two elastic solids, and thereby assumed small strains within the elastic limit. The contact radius a is considered significantly smaller than the radius of curvature R, and the two contacting surfaces, as depicted in Figure 1, assumed to be non-conformal.
